How Induction Heating works ?

- เผยแพร่เมื่อ 2 ก.พ. 2023
- Induction heating is a process where an electrical conductor is heated by electromagnetic induction. An alternating current (AC) is passed through a coil, creating a changing magnetic field. This magnetic field induces eddy currents in the conductor, causing it to heat up due to its resistance. Induction heating is widely used in applications like metal heat treating, forging, and cooking due to its efficiency and precise control over heating.

The direction of magnetic field is incorrect in the wire field demonstration, sorry for this silly mistake.
thank you fro this video, anyway. it was useful!
Sir very well explained but is there any disadvantages I mean environment related or out health related or something?
Yes
It’s correct for electron flow.
Good evening
Your effort is not wasted , This is an example of most clear demonstration.
Constructive criticism- I recommend explaining what a Lakh (one hundred thousand) is since this video is aimed at a worldwide audience, It's an unknown term for non desi people.
Had to Google 'Lakh' - that was the most challenging part of the video.
I have an induction cooktop, like the one you demonstrated but older. Had it around 7-8 years. No problems. I mostly use it to make pasta. Boils a pot of water, 3-4L in about 15 min. The pot is aluminum but has a steel plate pressed into the bottom to make it work with induction.
btw. Cast Iron is the most efficient cook ware for induction - ty for the cool 3D-Animation and explaining! Greets from Germany!
You forgot that the magnetic field should grow and shrink as well. Induction cookers are not just using DC that changes polarity, you're not going to generate eddy currents that way. They use PWM DC, like a DC trying to emulate an AC waveform. You still need the magnetic field to grow and shrink gradually (gradual but also fast depending on the timing frequency) and not just fix them in place with changing polarity, to make eddy currents, so you will be able to heat up ferromagnetic materials. You need a magnetic field that "scratches", like how you scratch your belly with all five fingers by spreading them apart then clawing them together to a tinier area then spreading them apart again, etc.
Now I know how to scratch my belly. Thanks.

Not everyone understand "lakh" just FYI. Good video though....thx for the hard work....as someone who completed Commerce Graduation more than a decade ago, your video made it very easy to understand.
Also loved the short and crisp length.
Lindo vídeo! Parabéns! Desmontei meu fogão de indução e ele é igualzinho! Por favor, continue produzindo vídeos legais e educativos como esse.
Anytime I have a Bluetooth headset in while cooking on Induction I get those craaaaazy sounds 😂😂😂😂
Excellent explanation and amazing 3d models!
It is very helpful in understanding the mechanism of induction heater ❤️👍
I first time heard someone say the word "lac"on TH-cam in my entire life.
I use it daily.
Well explained with detailed graphics....❤❤❤
Really enjoyed the whole duration... Efforts worth it! ❤❤❤
Fantastic demonstration. Good job and thank you.
I wish there would be a 1000-Like-Button! Well done, Sir!
❤
I just lost myself by your charming explanation.
Awesome! Thank you. Nice work!
Amazing animation for quick understanding.
Nice one
I have a nice five-pad induction cooktop at home. I'm currently a couple of thousand miles away caring for an elderly relative. And the relative's house is natural gas. Oh, I *_loved_* cooking on natural gas when that was the best of the best. It ain't anymore!
So, I'm currently stuck with cooking via natural gas. I'm such an induction snob now.
great video
I like it thanks who made it
Very useful
It's like rotating a magnet underneath a pan 50000 times a second (N up/S down S up/N down), but it uses alternating current instead of mechanical rotation of a magnet (which may lose its power over time)
Thanks for good explanation!
Nice efforts
Your efforts is appreciable, make more videos about physics
A wonderful animated demonstration..

Awesome Content
Fabulous animation 👏
Wow, great animation and story telling.
Cool explanation, thanks!
Mazing and simple video! Lots of respect!
The clearest explanation ever
Amazing very helpfully thank you so much
Induction heater are useless if you place an aluminum pan over the coil!. Please include this in the explanation. The magnetic field generated by the coil cannot generate eddy currents or induce a field in some metallic container over it.. That is why the instruction that go with the appliance is it requires that you use induction cookware only.!
This is the future of cooking maybe😅
What a fantastic explanation with animation!
I got knowledge about induction from your video 😊😊♥♥♥

Greetings from Romania
Good bro
Great video… I finally understand how this works! Keep up the good work
haha no you don't trust me :)
Nice.. I've had to watch several videos in an effort to try and understand how induction heating works. This video filled in some gaps. I think it's only missing one thing. To my understanding, the heat is generated by the alternating of the magnetic fields, which cause the atoms to excite (in the metal object/pan), ramming into each other (like bumper cars), and the friction of those atoms moving about, is how the heat is generated (in the metal/pan) . I think that is what the Eddie currents are, that you mention, If my understanding is on track from everything I've been watching.

Thanks for the info! This video clearly left out the most important part of how it actually heats up the pan 😂 I watched it several times, but it skips that most crucial bit of information...
Stunning rendenders and explanations
Wonderfully explained, Thanks a lot ❤
Thank you❤ very clear explanation, you are awesome
Fabulous video
very well indeed!
Got relief when one english channel dint said 1 Lakh instead of 100 thousand
I was really un aware of this phenomenon.... Liked...Subscribed...Amazing...👍👍
Thank you
Very good teaching. Thank you sir 👍🙏🏻
Yes
Very nice
Nice 3d animation! You have really clarified the workings of an induction cooker in a simple way. Can you please produce a similar video to explain how an infrared cooker works that allow to cook food on nonmagnetic cookware as well? Your effort is much appreciated 🎉
L000😊
Hai 😂🤣
i wonder what kind of software did you use to create this amazing video?
Nice video, thank you for sharing it :)
does it still work if we replace the inducting pan with plastic pan or any other made of non-inducting material ?
Fantastic....
Great animation!!!! Well done
Hats off to you sir ❤ thank you
Intresting thanks for sharing
You have new subscriber, plz continue making videos like this.
best video available🖤
Anyone else thought that thumbnail was a motherboard with a weird cooler at first ? 😂
This answers my question about whether the current running through the coil heating element is AC or DC. It’s so obviously AC.
It isn't. It's DC.
The glass bowl doesn't work because its non ferrous. It has nothing to do with being an insulator or too high of resistance. You need iron which has unpaired electrons in the d sub-orbitals which get manipulated by the oscillating magnetic field. That's why you need to put a magnet on the bottom of your pan to see if it will work.
He said "simple" : resistance. For professionals (as I understood) "means" magnetic permeability. If the material has greater magnetic permeability, the greater will be the conductivity for magnetic lines of force. Ferromagnetic materials have the highest value of magnetic permeability. Iron is a ferromagnetic material, and has the highest value of magnetic permeability and can be used for this cooker. :)
@@sanwomashi1751 What about using holmium?
is the. pot also gets AC current?
Very nice, thanks for video
thanks!
Awesome
This almost looks like wireless charging.
It's not clear actually. So, magnetic field changing in the wire creates electric field in the pan? Which also oscillates meaning electrons move inside the pan back and forward 15k times per second. Since pan has resistance, each time electron moves it actually spends the energy on heating the pan itself so the pan overall increases in temperature. Right?
Thank you!
Does cast iron work on inductions stoves ?
It would destroy any electronics accidentally swung over it, including smart phones and smart watches people are holding near it, by inducing a current in them, frying them from the inside, using the devices own wiring and loose electrons catching the waves, to do it!
Thanks!
0:21 the direction of magnetic field was wrong. Great vid tho
Thanks for making this video. Please make video on induction cookware
Hello , thank you very much for your video . Can you please tell me the software that you used for making the animation and the video editing , thanks again. have a good day.
Its a very good explanation. Thank you.
So as per the video the heat in the Cooking pan is not transferred heat from any other coil , its a direct heat generated because of the eddy current produced inside the Cooking Pan.
My Question is :
Than why it doesn't harm us when we touch ( Human body) the cooking Pan on the induction stove when it is having current inside it (eddy current) while cooking ?
Im not challenging anyone, its just my genuine doubt, hope to find the answer
Thanks for your sharing
Fun fact: he got the field's direction wrong xD 00:18
(ik that was just a mistake)
Good
Ensure that your cookware attracts a magnet .... then induction works best ! ........... DAVE™🛑
So would stainless steel pans work on this type of hob.?.?.?
Thanks 🙏🏻
How will the electronic oscillator, and other electronics fare in the long term adjacent to hot temperatures?
Short answer to the question in the title: it doesn't.
I bought an induction stovetop. The manual explicitly stated that it's designed for cast iron, cast aluminium, and stainless steel pans. I found that out of all our cookware exactly matching the list, only the cast iron skillet worked with it, but it was laughably poor at maintaining heat. Then it stopped recognizing that the skillet was present and relegated itself to the landfill.
The cost to the environment of manufacturing the device was many times more impactful than the cost of continuing to use natural gas, with all the attendant problems of mining and refining it.
It's a sham solution, and cause more harm to the environment than continuing use gas, and just cooking less.
Oh I forgot to mention that it would only heat a 10cm disc of the skillet. Not the whole thing. So one pancake at a time, or one burger, or one egg, or one slice of bacon, cut on halves.
Also, I use the microwave oven way more than I use the stovetop.
جميل جدا شكرا
My induction have temperature limiter. I cant cook on max. power more than 60sec. Can I mod some thermistor inside?
