I've used such cooktop years ago. Infact, induction cooktops have become very familiar to indian households, although as an emergency alternative.
I was never able to understand how it worked. But this 12 years old and mere 2 minutes long video was able to explain that so easily. Thank you for this well executed video.
Learn more in most 2 min videos than I did either time in college.
The heating occurs due to “Eddy” currents and Hysteresis. Hysteresis heating also occurs in ferromagnetic materials and is a less significant in aluminum and copper because of their high conductivity.
Thanks, Megan
Hello Devin Sikiric, Thanks for your interest in our creative induction cooking process. As far as the pan temperature goes, it would still be hot and could burn you. Since the pan would absorb the heat from whatever was being cooked or even boiling water, it would reflect this temperature so be careful. What is neat is that you could place a paper towel between the cooktop surface and the pot and the paper towel would not scorch at all. I hope this helps!

1:34 i just loooove turning things on haaaa
FurnaceRepairToronto - Great! Glad to hear this video helped. Thanks, Michelle with GE
I don't get it... GE commented, yet they weren't chastising people because of their race or political affiliation. This isn't the GE I know.
Hello Josh, you are so right! I love the technology of induction cooking and think it is a plus for any kitchen. Thanks for your positive comments. Sheree with GE
My friend bought an induction cooker recently and I'm impressed, I know the method was proven a very very long time ago now but it's like cooking by magic. It reminds of seeing other material specific reactions and some very strange effects possible when tinkering with electromagnetic waves and fields. Thanks for the vid GE.
Thanks for sharing our fascination, Brian!
"iron molecules". Great job GE.
no one cares
Ha ha, something rang dissonant when he said it and you brought attention to it.
No, induction is not like a microwave. It uses a coil to create an electromagnetic field of energy, which then passes through the cooktop to the pan. In order for a pan to work on an induction cooktop, it must have some iron to connect to the magnetic energy.
Thanks, Megan from GE
The question is' why does only ferromagnetic iron work on an induction hob. And don't say "because it works by magnetism", that's not a good enough answer. They work by induction, currents will be induced in any conductor place on an induction hob. Stainless steel is a worse conductor than pure iron, but the magnetic Stainless steels work and the non magnetic ones don't despite similar iron content. So what is the physics behind it? Oh and the answer is only partly due to hysteresis.
Hi Donald - we have a link for you! Please visit our Induction Cooking site at the following link - it answers questions about this type of cooking:

Thanks for checking -CC
David - thanks for the comment! At this time, we do not make an indoor, built in grill/barbecue.
Thanks, Megan from GE
Ingenious idea. Found it ideal for caravan use in summer as it stays cool. Only the utensil heats up. And that may heat the cooktop up. But no heat comes from the induction
Gameboygenius - in order to create the magnetic field and heat the cookware, the bottom of the cookware must have some iron content. The best way to determine whether a pan will work is with a magnet. If the magnet sticks to the bottom, the cookware will work on an induction cooktop. Hope this helps!
Thanks, Megan from GE
Hello Arxsyn, Thanks for your interest in our GE cooking products. Both the GE induction and our microwaves are very safe, but 2 different types of heating. Induction cooking, like our video shows, uses an electromagnetic field of energy and a pan with an iron-based core. The microwave uses non-ionizing radiant energy like radio waves or visible light. In sufficient concentration microwave energy generates heat. Both are safe and user friendly. Thanks for your questions - Sheree with GE
Interesting thar I know serious scientists who refuse to own a microwave, despite surely knowing it can't really "get you."
Strangely, I did feel a sort of warmth/pull putting my hand inside a microwave right when I turned it off. There's a plate in my right wrist.
I notice that people worried about microwaves are never worried about electric lights or cell phones. Haha
Strange that anyone should have to explain the difference to people much smarter than you are. It's not a 1940s shoe fluoroscope! My dad used to see those all the time. Still alive. Ha.
Tho, I did have an aunt who used to sit in front of an older one (70s) and she got cancer of the lymph nodes right at the hight where the micro was. It's obviously not indicative of anything, since everyone smoked like a chimney back then that I remember. Not to mention the margarine (yuck), asbestos (til the mid- 80s, Armstrong told me) and lead all over the place. Oddly, still here, almost 50 years later. Lol
Might very well have asbestos in the house today. It was very brittle and extremely strong as I recall. Black adhesive used (aren't they all black, even to this day...?). That flooring will easily last 60 years with little to 0 sign of wear. . Haha You should see my gramma's stove. It's got to be 70+ years old. Ours, a modern machine? Maybe 15, tops. So, maybe lead and asbestos are good for you. Lol (you know older people never want to spend money on anything or fix it unless they REALLY have to)
Hi sintoniza2z, Thanks for the great suggestion and your interest in our GE products. I will be glad to pass along your comments to our product managers. - Sheree with GE
Hi David, You are right! The induction cooktop uses a high-frequency coil, located just below the cooking surface. This coil produces a magnetic field that causes the electrons in the ferrous metal pan to vibrate, which produces heat. A fabulous way to cook! Thanks for contacting us. - Sheree with GE
Hello Rabone, you are correct the GE induction cooktops are easy to use and are completely safe. Enjoy! - Sheree with GE
Hi mickycheese27 - actually the pan needs to be magnetic to make the burner operate but the pan does not actually stick to the bruner. So an iron ring will not be an issue and there are no safety risks.
Thanks, Megan from GE
Hi Musikdoktor, I will be glad to assist you with your questions. The induction cooking is very safe and the pans will not stick to the cooktop. It is just the field of energy that creates the heat; it is not actually a sticking action at all. I hope this explains the process a little more thoroughly. Enjoy! - Sheree from GE

God bless you
Thank you! Very educative
Smith overdosed, thanks for your comment. We appreciate your feedback. Alison with GE
@ImJustSlime If a rare-earth magnet (REM), such as neodymium, is smaller than the minimum pot diameter for the particular induction element, then nothing will happen. This goes for things like spoons, forks, coins, etc. The cooktop has a sensor that only allows activation of the induction element when a pan of the right dimensions is placed on it. Hope this helps! Thanks, Megan from GE
@ruwan591 Sorry, unfortunately you can't use the non-magnetic pressure cooker on the induction stove. Thanks, Megan from GE
If I ever become a physical science teacher I am most liky gonna use this to explain induction to my theoretical future students
Don’t do it! It’s a trap!
Induction cooking uses a high-frequency coil, located just below the cooking surface, that produces a magnetic field that causes the electrons in the ferrous metal pan to vibrate, which produces heat (Like the friction when rubbing hands together produces heat to the hands). This is the only cooking method that directly uses the cookware as part of the cooking system. Magnetic induction cooking requires the use of cookware made of Ferrous metals, like iron or steel, to which magnets will stick.
@trailkeeper No. Using a magnetic plate between the induction heater and a non-magnetic pan will not work.
And turn it on HAAAAAAAA
I thought wtf until I watched the video :-D
really good video, no unnecessary bs.
No worries! You will not experience a shock. Thanks, Megan
Love it! Im your biggest fan
@EvasiveEvo Hi! Here are a few suggestions for you:
Use the smallest burner if not already
Try a thicker bottom pan. One with an aluminum core will distribute the heat more evenly
Hope this helps! Thanks, Megan from GE
Great explanation
Learn something new everyday...
thanks for this such a educative video
Good question! Actually, induction does not use radiation like a microwave, it uses a magnetic field. No impact to food unless it contains iron fillings!
Thanks, Megan from GE
Georgie Daniel - Induction is considered the most energy efficient surface cooking method. However, for helpful hints to lower your energy costs when using any surface units, please visit our GEAppliances website and type "range energy tips" in the search field.

these are awesome
Nice example and experience help me to develop commercial cooktop in 220 volts
@siffudy Cookware for induction cooktops should be made of magnetic stainless steel, cast iron, enameled steel or a combination of these materials. More information can be found at geappliances. com. Hope this helps! Melissa from GE.
I have one. It is awesome!
Thanks for sharing, Vikinglord1967! We absolutely agree!
will it cause cancer? I heard it will cause cancer
MasterofPlay7 did you find out if it causes cancer??
Very nice video!
internetzwemmer - Induction and standard ceramic cooking produce the same amount of heat. The difference is the process and speed. Unlike radiant cooktops, induction cooktops create a magnetic field, which in turn heats up the cookware. This means that induction cooktops can heat cookware instantly. As a result, induction cooktops are faster than radiant cooktops. Thanks for asking! - Michelle with GE
I'm spreading the word. You can get Induction difusser plate which makes ANY cookweare work!
Spyderkat - The GE induction is very safe. The induction cooking uses an electromagnetic field of energy and a pan with an iron-based core to create heat. The induction units even have temperature limiters which keep the units and the cooktop from overheating (such as when a pan would boil dry). This cooking is very safe and easy to use and does not create any other forms of radiation. I hope this helps! - Sheree with GE
Thanks for your reply sir
BtW people these cookers are GREAT!!!!
Well that sounds simple enough
I was 4 when this video came out.
Hi, Jackson. Thanks for your comment! We hope you enjoyed our video. Induction cooking has been around for quite some time. It is a terrific way to heat food. Please be sure and let us know if any questions come up. We are happy to help. Best, JP
I can't wait for the next generation of this stuff, as you could literally have a range top an inch thick total. I would suggest a rework of the coil(s), as we are still using Tesla based standards, Rodin's work MIGHT be something to look into, though a layered fractal based coil system would be better (and thinner). It doesn't exist....but..hey, that's why you work on it (like I do).
Good explanation understandable to common man too ! Any other cooking methods available using less energy and Electric bills?! Welcome for more information please.
@CrapPolice Yes it is.
Thanks, Megan from GE
I have a portable induction cook top.. can I pull a wire under my induction cook top while my induction cook top is running?
Priyanka Gavankar yep, tried it earlier, everything's good
@@slyyellowfox thank you
Priyanka Gavankar Oh uhmmm. I hope everything alright cuz I'm honestly not sure. I lended my phone to a friend so he could watch some vids and I didn't expect that he would comment
Current induction cooking systems are only efficient on steel pans due to the frequency needed to “couple” with the pan (match pan resonance). An Aluminum or other highly conductive or different material pan requires a resonant frequency multitudes of frequency magnitude different (like 10 times) or more than required for steel or iron. Current technology does not have a practical or efficient means of generating large amounts of power over such a vast range of frequencies.
@chuym249 Actually, that is not true. If the pan is not of a magnetic content, no heat will be produced. Thanks, Megan from GE
Damn I'm getting an induction cooker asap😘😂
@GEAppliances That wasn't the question posed by this person. The question was what WOULD happen if a rare earth magnet was placed on it. Just answer the question if you want to be helpful... you replied something completely irrelevant, about a sensor. You should address what would the cooktop do if the sensor thought it was a pot. What would happen in that case?
@ruwan591 You could always get a small block of iron and drop that into the bottom of the cooker. Might end up melting a hole in it, though.
Just explained as simple as that
Spyderkat - You are right this is a great and exciting way of cooking. While the cooktop does not get hot, the pan and food will definitely be hot and you should use the necessary cooking safety precautions. I would recommend that you visit our GE Appliance website and type in "induction 101". We offer some great information for you there. Thanks again for your interest! - Sheree with GE
There are so many types of stainless steel stock pot on the market. 304 grade, 430 grade, or 205grade.
I'm choosing a big stainless steel stock pot to cook meat stew. I will be using it on an induction cooktop.
Is it correct that one material conduct more heat than another material on induction cooktop? or as long as they are a little magnative, they all have the same cooking speed?
I'm wondering if the iron content matters the speed.
+Yinan Wang We are happy to help. In order to create the magnetic field and heat the cookware, the bottom of the cookware must have some iron content. The best way to determine whether a pan will work is with a magnet. If the magnet sticks to the bottom, the cookware will work on an induction cooktop. Thank you for your great question! JP
Does the electromagnetic waves enter into the cooking vessel?
Yes the electromagnetic field heats the cooktop: www.geappliances.com/ge/cooking/induction.htm
@TheZenPerspective "How long has this technology...been around? Good question. The first patents for induction cookers are from the early 1900's. Frigidaire, then a division of General Motors, showcased an induction cooker in the the 1950's on a touring GM showcase in North America. The induction cooker was shown heating a pot of water with a newspaper placed between the stove and the pot, to demonstrate the convenience and safety. This unit, however, was never put into production.
So in other words....witchcraft.
no. magnetic resonance
You have just exposed them
i guess an alien technology..
So that's how she brought Jon Snow back to life..... just shook him real fast.....
Rebecca Lopez It is safer for the elderly cared for at home as well as young children. If people love computers, don't see why this is not the most popular thing since sliced bread. It's Mr. Wizard in your kitchen. Your pots are also easier to clean, no build up of natural gas residue.
@L1J7E thats very quick i would get one but i cant as i have many reaoson against having one but i like to watch the video and see how it works its sort of satifiring
so isn't there anyway I can use a Full Al pot? I have a Pressure cooker made from fully non magnetic bottom, guessing its Al, is there a way to use it?
@raynarks I got one and its amazing, boils water under 30 seconds!!!
Really? Cool.
"and it's the friction between those molecules that creates the heat"
uhm NOPE.
What do you think it is that creates the heat? And why iron, but not copper or aluminum?
Kenneth is right. its not friction, its eddy currents.
In TH-cam you'll find all the answers you may want.
@@olivier6840 And if you listen you will hear a small hummm. That is the vibration it will go on & off as temp is met.
@@olivier6840 Iron is not a molecule it is an Atom. A molecule is a neutral group of atoms made up of different elements. For example water is a molecule made up of 3 atom, 2 hydrogen atoms and 1 oxygen atom. I literally haven't done Science in 5 years ...
I'm thinking about the same thing. I'm going to try later
The resolution only 240? Thats is too low 🙁
It’s an 11 year old video 😂
Too simple explanation
Induced current and the joule effect generate heat
gotta get those errrn pans
You've got to try pressing 5 when the video plays, if you like the way he says iron.
Do the pans have to be fully flat
put a very fine wire coil on this and see if lightning jump between the ends :)
Why it does not work when utensil is empty or cotains solids such as bread slices. ?
@hughezee Based on recommendations by NCDRH, an agency of the Federal Government, we are confident that there is no risk to humans from magnetic fields produced by the product. Thanks, Megan from GE
@Eat, Laugh & Design no you haven’t. You’re probably thinking of resistive elements
I recently purchased an induction cooker .... when i placed induction base pot on it - i just put a tester to see if current is passing or not as its connected via 230v - The tester light glows in red showing current is there ..... will it give me shock if i touch the pot?
made in china will kill ya, scro
nice tutorial
Hello Eric, induction cooking is super cool. Thanks for watching and posting your thoughts! -SF
I'm 90% sure this was a training video for GE employees lol
@GEAppliances it will work but takes a lot more time to heat the food.
Do you think it is possible to change an induction cooktop from 220V to 110V?
I would recommend checking the installs for electrical requirements but we cannot recommend deviating from those.
When will the GENX release
Should one obtain special induction cookware? Are there special cookware available. Can a cast iron pot work?
Hello Kerry, thanks for reaching out to GE Appliances and your interest in our induction cooktops. We have several helpful links on the recommended cookware including what we suggest about cast iron: products.geappliances.com/appliance/gea-support-search-content?contentId=17368 and products.geappliances.com/appliance/gea-support-search-content?contentId=16895 I hope this helps! -SF
How about the safety regarding the high EMF? Is it more than normal stoves? How does it compare to, say, electric heaters?
Isn't it always a trade-off? I mean, gas has combustion components that have to go somewhere...and they seem to take longer to work in comparison (if the video wasn't paused when recording), so if boiling water takes much less time...?
correct me if i'm wrong.. and sorry if my english is not good. during heat pan stick to the cook top? how hard stick to it? I ask because maybe it is also a good security option to avoid kid accidents with a pan with oil or hot water..
depends on the stove.
really? GE can only manage a 240p upload? Is there a reason for this? Well at least it's progressive. I suppose it could have been interlaced. Thanks for the info though. That is providing value. good job.
Does the friction of the pan's molecules cause the pan to wear out?
Nope. Friction doesn’t do that on a molecular scale.
@@ahappycoder2925 thank you
Interesting
@Mrfordtoyou
i kept replaying that :D
Damn, TH-cam has been a round awhile!?
Is there anyway that I could email an engineer or speak with one? I teach an independent research class for young / early teen scientists. It seems like there is a TON of science here and much to yet discover. Also, it seems like it is safe for kids to be around. I'd love to be able to connect to GE engineers. I can vet/credential myself if I knew whom to contact. Thanks.
So dope
Is this a more energy efficient way to cook?
We don't have a induction cooker but if we buy one we have to make sure that it's from the well known brands like GE, etc. so that we are not scam by the price from the unknown brands. Induction cooker is one of the most popular product use by scammers in the Philippines because of their amazing properties like they put a paper on the induction cooker and a cooking pot on top of the paper and shows that the water boils without burning the paper to demonstrate about its safety but they charge you Php 60,000 (US$1,350) for a double burner.

Thanks for your interest!
Subtitulos,por favor
in an induction cooker, a coil of copper wire is placed underneath the cooking pot. An alternating electric current flows through the coil, which produces an oscillating magnetic field. This field induces anelectric current in the pot. Current flowing in the metal pot produces resistive heating which heats the food.
Now my question is, when current flows through the vessel, won't we experience a shock when we touch the vessel..???
Energy Conservation hard to answer question. Our electricity is generated primarily using natural gas. Generally speaking, would I be using less gas if I used gas or an electrical induction cook top? Anchorage AK
