A Ring Clock
There are many other forms of watches for instance wrist watch, pocket watch etc. The evolution does not end to this so there is another innovation of introducing a new concept of watch i-e a Ring Clock or Ring Watch. The team behind this idea has launched a funded campaign in support of this idea to bring into the market.

As watch is also available in a mobile devices and also there are many expensive watches of different brands. The people demand for new innovations and thus in essence of this a Ring Clock has been introduced as a new concept in this fray of watch.    

The ring clock is designed by Gusztav Szikszai in 2011 for the competition. Ring clock is impossible to prepare it now but may be feasible in 10 years. It became into reality just two years before and it is far from its completion time. Ring clock is wear as a ring in a finger.

It is designed in such a way that it consist of two rings, upper and inner ring, intact in such a way that it looks like a one solid chunky stainless steel ring. The upper portion of ring watch relates to hours. The lower section represents minutes and the last segment is dotted one that corresponds to seconds.

Dynamic Versus Static URL's in SEO

Dynamic and Static URL's in SEO

From previous discussion you know that how much the search engines dislike the images in a website from SEO point of view. All efforts of making the website fascinating by putting images and flash videos on a web page by designers become useless. One more important thing is that the dynamic URL’s are also disliked by search engines. Search engine did not like the URL’s of this type ‘ =18’. Such URL’s are also disliked by the users because the website is not cleared that to which content it belongs. In comparison to dynamic URL’s, the static URL’s are much better. The dynamic URL’s are not consistent which means there are some sites in which a person has to submit forms. In this case it is very difficult for the search engine to categorize it and it is very difficult for search engine to crawl on each form for every different person. These kinds of pages did not exist in the directory of search engines.

If there is an already page submitted by a user and it was in the directory of search engine, then next time when a person log in this page  and if that page contains so many questions and symbols in it then it was skipped by the search engine. Once there was a time when search engine never searches the dynamic pages but now a day it started indexing them but the problem is that the process is too much slow as compared to index static pages.

You also don’t have to stick with the static HTML pages because there are some sites that needs database and that sites have an address in dynamic only. You can overcome this problem by serving your pages and your users to the search engine in a format that was easily index by it. One of solutions to this problem is to rewrite the URL in such a format that was friendly to the search engine so they will appear in a browser just like a normal static HTML pages.   

Backlinks Categories Imperative in SEO

Backlinks Types Significance in SEO

Backlinks are so much essential because it indicates the popularity of that site. Search engines like Google gave importance to those sites that have more backlinks and considered them a more relevant site than the others in a search query. There are two categories of backlinks that play significant role in SEO.

Meta Tags Substantial in SEO

Meta Tags Significance in SEO
Importance of Meta Tags in SEO

Meta tags also play an essential role in search engine optimization (SEO). It describes the whole summary of your page. These are not visible by the human beings but only searched by search engines. The Meta keywords and Meta description are two of the most substantial Meta tags. The Meta tags are in the contents of your page. There was a time when search engine gave significance to the keywords in Meta tags that are imperative for the ranking of your site but now a day’s algorithm has been changed a lot.

Description Meta Tags in SEO

Description Meta tags are those that best describe your website. You have to write a brief description in this Meta tag about your website so that search engine like Google will display your description on the main page.When it searches and brings more visitors to your sites. When you write good description then you will be able to get more traffic to your site.

Keywords Meta Tags in SEO

Keyword Meta tags includes a list of possible common phrases that best describe your website and you have to write them. Some of the search engines will not gave such importance to keywords Meta tags but there is no shame in it to try some short keywords like ‘colour or color’ and also include some wrong spelling keywords. This is a chance to boost your website a little then why you should avoid it. 

Robot Meta Tags in SEO

In this tag you have to specify that which pages you do not allow search engine to search. There are some contents on which you are working and are not totally completed and if you want that these pages must not searched by search engine then you have to write the list of those pages in robot Meta tags. 

Selection of Suitable Keywords in SEO

Choosing Of Proper Keywords in SEO

Picking of Legit Keywords in SEO
Collection the right keyword is the most important and initial step of optimizing your page. When you are successful in optimizing your page by collecting the appropriate keywords then you are on the right track of SEO otherwise you will be on a road with so many bumps and you just waste your all time and money. You have to gather the proper keyword according to the queries entered by different persons and before selecting it there should be a long list of it. You should choose those keywords that best describe your website.

It would be a rare chance that you get your site at the top by using a string of one word in a search at once. As you know that now a days the webs are full of lot of pages so it was very difficult to attain your site at the top by using a string of one word. So using at least two or three strings of word will be beneficial.

For example: if your site is about ‘food’. Then you don’t have to choose a keyword of just only ‘food or foods’. So you have to choose like ‘food recipes’, ‘cooking foods’, and ‘delicious foods’ as a keyword. There is a chance that someone can use these words also but don’t worry about this so you have to be very careful about choosing keywords that are not surplus in amount and should be unique so there should be a less competition between same kind of sites.

The most important thing you have to do is to choose those keywords that best describe your contents of the page and you know very well that what kind of phrases the user uses in a search engine. Put yourself at their place and you will know how a person searches for anything.

One thing you must be careful about keywords that you don’t have to only consider that how much searches has been made in a month but also keep in mind how much is the relevant information in your website.

Number of Keywords inn SEO
Amount of Keywords in SEO

The next step after choosing the keyword that best describes your web page is the density of keyword you use in the whole web page. Greater the numbers of keywords you use in the rest of your web pages higher are the chances of getting top in the search engines. There are no such rules or restriction of using surplus quantity of keywords but you can use at least 5 to 10 keywords but not hundreds of them on a single page. When using huge amount of keywords in a page the search engine will consider it as an artificial thing and the adverse effect of this is that the search engine abandoned your page because that strategy of manipulating so much amount of keywords in a page will considered as illegal.

Places of Keywords in SEO

The keywords are more important at the place of page title, main headings and in the initial beginning paragraph rather than using so many keywords at the bottom paragraph of the page. When the number of keywords you use in the page title, file name, sub headings, paragraphs are equal to another person then the only thing that differentiate you is having a keyword in the URL. That will increase your ranking.

Keywords for URL, File Names in SEO

The domain name and the URL name play an important role in SEO. For instance assume that your site domain is about ‘food’ or ‘foods’and site tells mainly about how to cook foods then you have  to choose URL name as ‘food cooking’ rather than ‘Recipe making’. The first one URL has more importance than the other URL because two of the keywords are used that is relevant to the content of the page.

It is best to use at least three keywords in the URL because it is very difficult to remember such a large URL for anyone and also for himself because websites are not only searched by you but from all over the world. Keywords also play an important role in the file name because some of the search engine gave importance to the file names. Let’s have an example suppose one of the site names is ‘’. The second one is ‘’ and the third one is ‘’. Whereas the first one is better than the third one but second one is better than both of them. The advantage of file name is that they are easy to change.

Keywords for Page Title in SEO

Keywords also play a keen role in page titles. Most of the search engines like Google display the contents of the page by seeing the page title tag. One can also leave it empty and the search engine will open it as an untitled document. The page title can be as long as you want. If you are working as an SEO then you have to write in a page title tag.

Keywords for Headings in SEO

Separate headings for each paragraph play an important role in SEO. It is useful when there is a keyword used in each headings of paragraph. You can use a number of headings by writing their lengthy names in the heading tag but a common sense says that too much long headings become worse so choose words that are less than 7 or 8. The most important matter you have to consider about is the displaying of heading on the page. The first heading will be considered as <h1> that has  a large font so if it is more than 7 or 8 words then it will go on next line that is not suitable for the search engines.

Content Significance in SEO

Importance of Content in SEO

Today most of the people are working on their websites and copy so many contents from other site to their site for the purpose of doing SEO that really deteriorate significance of content. The other thing they do is just posting some random keywords on their site page in content for the purpose of high ranking in the search engine. Both of these activities are wrong because a viewer spend so much time on your site and want something in return so write a purposeful content to get the attention of the readers.

Videos, Pictures uncategorized by Search Engines in SEO

Videos, Images not Categorized by Search Engines in SEO

As I told you before that search engines did not consider about any video, images, flash videos etc. It only searches your text in the whole page and that should be meaningful. According to your information it categorizes your file. For instance if you have a text in your page like ‘so many years ago’ then you have to write the description in the Meta tag and the search engine will rank that information. A day will come when the search engine searches your videos and images but this is just a dream come true.

Images Importance In SEO:

From a website designer point of view images are essential part of a page and considered them, most important content of the web page. Now the designers and the search engines are at different poles. From search engine point of view if the image is describing some information then that information is lost. It is very difficult to explain designers that using the links with anchor text are not only for the fanciness but these are mandatory part of the page. A designer should create a balance between images and the SEO and if you did not do his then your site will be lost on the internet so you can use some images for the decoration of site to some extent.
I did not mean to say that you should not use the images in your site page because the site that contains only text are also become boring for the viewer so you can use those images that just illustrate your text. Keep in mind that you can use images for the decoration but not for the navigation purpose and one more thing you should avoid the fancy texts with large fonts on your web pages. You should use meaningful name to the images rather than just displaying image1.jpg, image2.png, image3.gif etc. use short text for the images because using too much long words will look like stuffing of keywords and it look suspicious by the search engine.

Animation and Movies Importance In SEO:

The use of animation and movies are also not good for the SEO purpose. Just like images they are also not searched by the search engines. It looks fascinating to have a flash movie at the front page of the website from the designer point of view but from search engine view it is a SEO killer. If the whole incident about any topic was described in a flash movie then it is useless for the search engine. One way is to provide a HTML version to the search engine of flash movie but do not forget to exclude the original flash movie from categorizing by writing in a tag of robot.txt file. It needs more explanation for the beginners to understand so it was not written in this tutorial. A small hint is that if you did not do this you will be banned from the search engine.
There are so much rumour about the search engine like Google that it starts to search all the animation movies especially .swf format of flash movies that contain a unique Meta data. Avoid from using a cluster of flash movies and use less quantity with a short description in text format with it.

Frames Importance In SEO:

Frames also play a worse role in SEO. It was good to see that they are diminishing slowly from the web pages. If you go back 5 or 10 years then it was considered an important tool for the designers but not for the search engines. The problem is that the URL of all pages was same and it was very difficult for the search engine to categorize them and also did not know which frame was opened at which page. One thing that arise in your mind that by providing a link of other pages on one page will solve the problem but from search engine point of view it was a great hurdle for it. 
If you still persisting on using the frames in a website then you have to add some meaningful information that best describes your website in a <noframe> tag and also for the users whose browser did not support frames.

 Java script Importance In HTML Pages: 

It has a great importance in HTML pages. Everyone knows that to make HTML more functional you have to need some programming. As you know HTML is not a programming language for making of web and it cannot be used to store information in a database. So to make website more functional you have to use some other languages like JAVA and PHP. The search engines will never search the page that was encountered by the java script. It was very difficult to explain it in detail here.

Search Engine Boost Your Traffic Through SEO

SEO, Search Engine Increase Your Traffic

The most important way to increase your traffic to your website is to optimize your site by using SEO technique. This is the only way to make yourself visible to search engines and they will increase your ranking at top of the page. They will provide you more visitors to your sites and the companies will contact with you for their website advertisement promotions. The truth is that SEO is not only the ways to get high traffic to your sites similarly search engines are not only source of accumulating more visitors for your site. There are so many online and offline methods to do this but I am not going to discuss it in this tutorial but I can say you that this is the easiest way to do it by using these techniques.

 Submit Your Site To Search Engines:

When you have done the optimization of your site then there is a time come when you have to put your site to the search engines. You don’t have to do so much extra work for it but just only submit your site to the search engines and they will crawl your site. This is not exactly happen like this and not so much easy because it is very difficult to say that at which time the search engine will search your site first and only thing you can do is to just invite them. You just only submit your URL pages but this does not mean that search engine will hire your site at first glance. It might be possible that search engine did not crawl or visit your site. Any way you can submit your pages to the URL of these websites such as Google, MSN and yahoo.

 Submit Your Site To Search Directories:

After submitting your site to the search engines now you can submit your site to search directories. Search directories have list of search engines that searched according to given submitted information. They are different from the search engines in all aspects. First is that they are managed by humans and the site will never submitted after the approval of relevancy of information. Second is that you have to submit your site to these directories and you can stay in whenever you like.They did not crawl URL’s of the sites so you have to contact with them. The most prevalent search directories are DMOZ and Yahoo.  

Submit Your Site To Forums:

The other way to promote your site is by posting your links in the forums of other website. You have to find such forums that are of great interest for the people and are commonly used. For example if you like ‘electronic forums’ then write it in a Google search engine then you obtain a list of those forums that are related to electronics. But keep remember some of these forums did not allow posting the links of other website for the promotion. Posting links in other forums consume so much time but the reward is so good.

 Increase Traffic by Specialized Search Engines:

There are so many other search engines rather than Google, MSN and Yahoo which are used for the general purpose. There are some other specialized and general purpose search engines that are used for the increase of traffics. These specialized search engines are related to some topics that are educational, news based and tourism. Some of them are enormous sites and contain information about specific topic and also have a section of submitting the links of other websites. So when you find some specialized web sites then start posting your site URl. This is the most efficient way to increase traffic rather than getting at the top of Google.

 Post Links In Paid Ads:

Besides posting your links in specialized search engines, general purpose search engines, forums and directories you can post your link to the paid aids. The search engines accept payments of posting links to the paid ads. This is most efficient way to appear in the search results of search engines but you have to also keep in mind that people did not go for the paid ads and prefer normal ones. Also by giving money to search engines is just like bribery. Most of the people choose this way to get popular at least time but this is not the right way because people did not focus on such sites rather that appearing in a normal way in search results of search engines.

How to get traffic on your website through seo


Whenever a person write a query in any of the search engine then a list of possible websites will appear according to the query he or she enter. A person will obviously go for the first website that was at the top of page and considered it was relevant to him or her then a person scroll down a mouse to see other websites if the first one is not relevant. Did you ever think in your whole life why some of the websites are ranked higher? It is because of a technique called Search Engine Optimization (SEO).

IntellectualM Bracelet Examining Proper Hand Wash

IntelligentM bracelet monitors hospital staff hands wash 

IntelligentM bracelet scrutinizing healthcare workers hand
As it is surprising to hear that a chances of a person sickness are more when he or she is in a hospital. In HIAs when admitted to a sanatorium and almost 100,000 of people die annually. There is a one way to reduce such infection by examining health care workers to clean their hands after some interval of time and systematically. All this can be done by an intellectual bangles device that should be wear on their wrist.    
united state, one person out of 20 people is infected with

There is so diversity in that technology of addressing the hand hygiene problem. One of old method was the human observers that are situated at hand washing areas for observation of properly being washed. It is impossible to situate observers in all kinds of such places as some people swab their hand more properly when they are being watched.

The possible solution for this is a device named IntelligentM.
An IntelligentM bracelet can be wear by any person in a sickbay such as it can be used by nurses, doctors, workers, technicians and all other members that are intact with patients. The device possesses accelerometer connected with a microprocessor. The function of accelerometer is to detect hands movement and also application of hand sanitizer during washing.

IntelligentM wristlet consists of RFID tags located on it where washing or sanitization is required. If a person did not cleanse his or her hand for long interval or proper specified time then the buzzer beeps three times or once a time if a person washed hand properly. In addition to this it tells the record of a person washing procedure. If a person did not sluice hand appropriately then an administrator can check every person records for inspecting their hygiene where he or she had done infringement. It also provides time and location where lapses have been done.

According to MIT report that technology has been used in a hospital of Sarsota, Florida since last December and two more clients from the same state has adopted that device.

NEC Launches First Water Cooled Smartphone


Smart Phone with Cooling System 
You heard that phrase ‘my phone is getting hot’. It means that there is an extensive use of processor by means of an extensively used application in a mobile. Desktop computers have the capability of using water cooling system for their processors that prevent from overheating. So why could not Smartphone’s have such those qualities? The NEC has revolutionized a model Media X N-06E such a first water cooled smart phone.

The Media X N-06E has a processor of quad-core Snapdragon S4 Pro running at a speed of 1.7 GHz. The heat of that processor has been extracted out from sides of water filled heat pipe. This type of chip can be easily found in LG Optimus G Pro and HTC One but neither of them having the capability of preventing overheating related issues.    

The chip they used have the ability of clocking speed of 1.9 GHz but NEC is stuck to 1.7 GHz for that water cooled phone so that the use will experience new boost performance. The benefit given by NEC is that it enhances life of a chip and introducing a cooling sensation to a user hand.

The feature of that phone are tremendous acquiring of Android 4.2 application running on it, 13.1 mega pixel camera, a 4.7- inch 720x1280 OLED display, a battery of  2300mAh, water resistant & dust proof casing (IPX5, 8/IP5X) giving opportunity of submerging it into a water pool that is also good to prevent it from getting hot.   

As pink touch is given to that mobile with sparkle accessories, is commonly designed for the women by keeping it in mind. It is going to be release in Japan in end of this June with collaboration of NTT Docomo.

Edible Electronic Medical Devices like Pills


Edible Electronic Pills
Few years back scientist have developed such camera pills that can be swallowed but indigestible whose function is to transmit video of interior parts of body. By considering this thing in mind of researchers from university of Camegie Mellon, they developed such an electronic medical device that can be easily edible and partially eatable and there should be no persistent treatment in this method.   

The project is led by two professors, Christopher Bettinger and Jay Whitacre. Christopher is working on the biodegradable electronics especially that can be used for medicinal purpose whereas Whitacre has developed such a cheap, non-hazardous electrochemical sodium ion battery. 

Whitacre declare that my battery is comestible. One day Christopher came to my office and said to me can you eat your battery? I answered yes and the history is explained after this. My battery can be easily eaten because it needs low power as need for the digestion of food and hence a perfect match.

The electronic gadgets such as sensors, drug delivering systems and tissue stimulating tools are placed in gelatin capsules that are powered by the palatable batteries. Such devices are made up of biodegradable memory shaped polymer and are enclosed in a folded manner in a capsule. When the capsule reaches in gastrointestinal area it dissolves after a particular time and after that polymer hydrate thus let the battery to flow electric current causing electronic device to operate.   

These capsules are taken like regular medicines. Such devices remain in the digestive system for about 18 to 24 hours and the functional lifetime would be one to two hours. Most of the components are digested like food and some are passed out without recycling them.

Bettinger said that most of patients feel comfortable in swallowing pills that have esculent electronics inside them. The key idea is to manufacture such nature friendly materials that are safe to use which we have done.

Fusion Solar System Increases Natural Gas Power Plants Efficiency


As solar power produces infinite energy but only demerits are its cost and sunlight because it will only work when there is a sun. By taking these two factors in consideration, Department of Energy's Pacific Northwest National Laboratory has developed a hybrid solar gas system that increases efficiency of natural gas of power plants and decreases emission of carbon.

The system consist of a parabolic mirrors that focus the sunlight to a chemical reactor that is (1.2x0.6m) in length and is lined with narrow channels that are 8.1 mm wide. The sunlight heat up natural gas in these channels nearer to the catalyst that converts gas molecules into carbon and hydrogen dioxide mixture called synthetic gas or syngas. There is a heat exchanger near to the reactor that accumulates all waste heat from the reaction and reuse it back to reactor until 60% percent of sunlight is converted into chemical energy. The test of that system indicates that a natural gas plant can work on 20 % more efficiency.     

PNNL engineer Bob Wegeng said that our system is capable of using less natural gas to produce same quantity of electricity as power plants are producing now. He also said that our system decreases the greenhouse gas emission as compared with the emission through fossil fuels.

It is known that the system will work more efficient in areas where the sun shine is more and it can be easily adapted to any natural gas power plant. For instance a 500 MW power plant needs about 3000 dishes of solar and also the synthetic gas can also be used to produce synthetic fuels for the vehicles

The PNNL test systems at its own campus, Richland where Washington is as a part of it to produce more efficiency to cut down the cost to six US cent per kilowatt hour by 2020 so there will be a competition with traditional fossil fuels plants. The Microproducts breakthrough Institute that is a research and development facility in Corvallis, Oregon has aim to develop mass producing system whereas industrial partner Solar Thermo Chemical LLC plan is to develop and manufacture that system before selling.

Terrestrial Multi-Junction Solar Cells


Terrestrial Multi-Junction Solar Cell
As technology has been revolutionised and getting advance day by day and one of the most important contemporary technology is the solar cells. It is a desire of every engineer to make environment green and they are trying every possible effort for the existence of such environment. One of the most famous Spectrolab that is a subsidiary of Boeing, known for the manufacturing of solar cells for spacecraft’s and satellites has now forwarding their attentions towards terrestrial solar cells for his name in the market of intensifying alternative energies. A California based company has claimed about efficiency of terrestrial multi-junction solar cells of about 37.8 percent without any need of solar focusing.

However Spectrolab and other companies have achieved high efficiency of solar cells by concentrating the rays of sun with help of mirrors on solar cells. The company said that they are able to produce such multi-junction solar cell with a high efficiency without any need of solar concentration.

The traditional solar cells are based on silicon technology whereas multi-junction solar cells contain different semiconductor materials that are interfaced with the help of a technique called p-n junction. Each material is tuned to specific wavelength of light to increase efficiency of solar cells.

It is not confirmed that which particular type of material is used in the multi-junction solar cell. It is just a news declared by the Boeing that an efficiency of 37.8 percent was achieved by using two or more materials in multi-junction solar cells. This will leverage the Boeing technology that manufactures semiconductor materials more trustworthy.  

The company said that we did not stop on our successes. Nasser Karam says that our company is able to produce high efficiencies of more than 45 percent under lower concentrations.

Biodegradable Solar Cells from Trees


The scientists of Georgia Institute of Technology and Purdue University have discovered new solar cells that are totally dependent on natural substances which can be easily obtained from plants and trees. Those solar cells have an efficiency of about 2.7 percent. These cells present on the substrate that are derived from the renewable raw materials and can also certainly biodegradable.

A professor named Bernard Kippelen from Georgia Tech College of Engineering has researched on this and expecting to have a defensible and renewable solar cells to make it function practically for the first time.   
A Kippelen has opened a new era for the engineers to make advancement in the technology of solar, based on the performance of organic substrates for future use. He also said that these organic solar cells must be recyclable otherwise we are just making ourselves less reliance on fossil fuels  because present fossil fuels technology through which we are obtaining energies from natural gas, oil and coil  sources but they are not recyclable at the end of their lifespan.  

Organic solar cells are assembled on a glass or plastic and it is very difficult to recycle them whereas Kippelen solar cells are contrived on a Cellulose Nanocrystal (CNC) that is obtained through trees and plants.
Solar Cell Fabricated on CNC
After the completion of life cycle of these solar cells, they are simply immersed in water at room temperature. After minute water is absorbed by solar cells, the CNC substrate dissolves and leaving behind the solar cells with its major components that can be easily apart.

Recycling of Solar Cells in Water 
Before dissolving of CNC substrate by a thin layer of organic semiconductor it allows the light to transmit through it, as CNC substrate is optically translucent. The efficiency of 2.7 percent is not sufficient as compared to recent technologies in solar cell completed by ‘Empa’. In that there is a clear demonstration of recycling of solar cells that are ecologically beneficial.
The researchers are still involved in trying to increase efficiency of those solar cells for the future use. Their next step is to improve the power conversion efficiency exceeds 10 percent similar to the solar cells that are fabricated on substrate of glass or petroleum based, said by Kippelen.

Induction Heating Machine


If you want to heat metal parts with high accuracy, high speed of work, consistent performance, 90% efficient, low noise, no fumes and without any exposed flames then the machine known as induction heating is most preferred choice for all industries.

The induction heating procedure is the most preferred one than any other heating technique. The induction heating system is good for industrial hardening, galvanising, alleviating, brazing and heat staking. This technology is also suitable for non-metals with proper setup. This technology can be easily fit for all manufacturing floors of industries and also whether the requirement is high heat or used for the fully automated plant, this is the desired solution for all industries.

It is a process of hardening, softening and jointing two or more different metals. The induction operation is also suitable for the non-conductive materials with proper setups. That procedure was used in a year of 1920’s in World War 2 where it was used for the hardening of machine engines in a mean time. On the basis of that preceding technology, induction system has been revolutionised.

It is a unique system than any other heating method because in other heating strategies like open flame, is directly applied on the metal parts but in case of induction heating, a heat is induced in the material by means of a current circulating in it.

Induction heating works on the RF frequency that is below the infrared and microwave frequencies. It means that heat is transferred to the material by means of electromagnetic waves. There is no contact between inductor and a material. The inductor does not heat up and a product is moved inside an inductor. The process will flow in a smooth way by repeating same strategy.

Faraday's Law of Electromagnetic Induction
Now I am going to describe how that process will work. It is just a fundamental principle of electricity. Consider an AC current is supplied to a primary winding of a transformer due to that magnetic flux creates in it. There is also a magnetic field arises. If the secondary coil is in the vicinity of magnetic flux created in primary winding then a current is induced in it. This whole process is simply called a ‘Faradays Law of Electromagnetic Induction’.        

Basic Setup
In the diagram shown to the right, simply constitute an RF supply source that sends an AC current to the inductor made up of copper and a metal that is to be heated is placed inside it. The inductor serves as a primary winding and a metal is considered as a secondary short circuit. So a magnetic field of inductor links with the metal and a closed eddy currents are induced in it   
Induction Heating Principle

In the second figure shown to the right shows the eddy current flow against to the resistivity of the metal that is to be heated and there is no contact between them. The heating can be applied to magnetic and non-magnetic materials and is known as ‘Joule’s Effect’.   
As there is no physical contact between them so the metal that is to be heated is placed in a liquid, away from power supply, in gassy atmosphere or in a space.

Advantages of Induction machine
  • Consistent Performance

Induction Heating Machine
The performance is consistent as compared to other heating methods such as torch or open flame heating. When you set up the calibration then the pattern of heating is continuous and constant.  Modern machines have a temperature control systems that turns on or turn off the power supply and providing constant results. It is also capable of providing temperature data of each individual part.
  • Maximum Production

A production is maximum as there is no time needed for it to warm up or cool down. A heat of about greater than 2000 F is developed instantly within the part in less than 1 second.
  • Minimum Chances of Rejection

As there is no direct contact with a flame and heat is produced in a material by the alternating electric current in itself. So there is s a minimum chance of rejection ratio and a part is placed in an isolated substance or in a vacuum to diminish the effects of corrosion.

  • Increase Durability

Supply heat to the specific part between two materials and increases the durability of life.       

  • Environmentally Friendly

No fumes of gases evolved and no intense noise during heating so it is friendly to the worker as well as for the environment.
  • Energy Consumption

It consumes less energy as 90% of the energy is converted into heat.
