- 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.

thanks for watching🙂🙂 - วิทยาศาสตร์และเทคโนโลยี
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.
yes
This is what an explanation video should be like. Not 10 minutes introduction about unrelated matters then 2 minutes of ads and then 2 minutes of the actual explanation people are looking for
"This is what an explanation video should be like."
Not really. The voice-over is AI slop. It's jarring how badly rhythmed it is; it's not how you would expect a person would speak. Also, it's presented as content made for viewers in Western countries but few people outside India know what a "Lakh" is. The uploader is obviously from that part of the world and with a poor grasp of the language he's trying to emulate.
@@StickerWyck My apology for not being clear on the matter. What I meant was that the structure of the video, as an explanation, was good. Content wise, it's up for debate. What I am really fed up with nowadays is that most TH-camrs spend too much time on unrelated nonsense at the beginning of the video, then ads, then this and that before they go into the actual explanation they promise (via the titles and thumbnails)
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.
Acch
Did you seriously refer to "using DC that changes polarity," ??
Starting to ending 😂
Bot, may be?
Well explained with detailed graphics....❤❤❤
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.
So make lakh an worldwide term ?
@@gauttamsinghanwal3054 tough task. Just like 99% of us say Kilograms instead of pounds (lbs).
Desi? What is that ;)
@@leegranite2920 Hindi word of native
nobody cares what a lahk is because it isnt a real word in the civilised world
Lindo vídeo! Parabéns! Desmontei meu fogão de indução e ele é igualzinho! Por favor, continue produzindo vídeos legais e educativos como esse.
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!
Does the alternating magnetic field uses more power or less without an iron pot? My small unit detects if the pan or pot is taken off and starts beeping.
An excellent, clear, and concise explanation - thank you. Though, for the rest of the world, 1 lakh equals 100,000.
Гарний ролик. Дуже зрозуміло показано що як і до чого; навіть не знаючи англійської мови, зрозумів майже все.
❤
I just lost myself by your charming explanation.
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.
Had to Google 'Lakh' - that was the most challenging part of the video.
Are you talking about how illiterate you are? 😂
are u stupid
100000
It is very helpful in understanding the mechanism of induction heater ❤️👍
Excellent explanation and amazing 3d models!
I am an EE with a MSE degree and this was a fantastic explanation. Keep up the great work.
A wonderful animated demonstration..
I was really un aware of this phenomenon.... Liked...Subscribed...Amazing...👍👍
Your efforts is appreciable, make more videos about physics
Awesome! Thank you. Nice work!
Amazing animation for quick understanding.
1:02 Battery expired, check it before it corrodes the wires! 🤣😂 Seriously though - that's a great looking video! 👌👏
Brilliant work 💯👏👏
Subscribed!!🎉
Fantastic demonstration. Good job and thank you.
Really enjoyed the whole duration... Efforts worth it! ❤❤❤
Thank you❤ very clear explanation, you are awesome
I wish there would be a 1000-Like-Button! Well done, Sir!
You have answered my question for years. Thanks for this explanation. I am your new subscriber.
Wow, great animation and story telling.
Awesome Content
Amazing very helpfully thank you so much
This is the clearest animation ive seen for this, thanks!
Very good teaching. Thank you sir 👍🙏🏻
Yes
Great video, so cool!
Nice explanation with animation 👌👍
Please do regenerative breaking!
Can I also cook rice in this type of heater with pressure cooker
Great video… I finally understand how this works! Keep up the good work
haha no you don't trust me :)
i wonder what kind of software did you use to create this amazing video?
What a fantastic explanation with animation!
I got knowledge about induction from your video 😊😊♥♥♥
Really super information. Love from India 🇮🇳
does it still work if we replace the inducting pan with plastic pan or any other made of non-inducting material ?
Wonderfully explained, Thanks a lot ❤
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...
Fabulous animation 👏
best video available🖤
Great animation!!!! Well done
Great well explained
Great and straight to the point video!
Some would like to know if the magnet field is directed upwards or just attracts the metal above it. Would it make sense to have a spiral element that can be used both sides? Are there metals that heat up more with the same power?
Nice video bro 👍
Does cast iron work on inductions stoves ?
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?
Since utensils containing food also carries current, is it safe to use ?
The clearest explanation ever
Nice, short & sweet :)
Excellent

What is the voltage generated on the cooktop and would you get ab electric shock on touching it?
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 😂🤣
what 3D software did you use for your video? Thxs
Thank you for your video
So would stainless steel pans work on this type of hob.?.?.?
Thanks 🙏🏻
Nice content!
Bravo.......ok ....say u want to use glass .......they make a heat plate for that.....cheers
Mazing and simple video! Lots of respect!
Hats off to you sir ❤ thank you
Wow, my mind is blown. We should make all houses standard induction heating
Nice efforts
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.
It's both. It uses a regular 50/60hz AC supply as input, converts it into DC than reconverted to 50Khz AC.
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
Anytime I have a Bluetooth headset in while cooking on Induction I get those craaaaazy sounds 😂😂😂😂
What do you use to make such an amazing video. Can someone Share the name of software with me please
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.
Very nice demonstration. Thanks
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.!
Aluminum is a non ferrous metal, therefore will not work with magnetic induction
How will the electronic oscillator, and other electronics fare in the long term adjacent to hot temperatures?
Great explanation. Thanks a lot.
I like it thanks who made it
Very useful
This is the future of cooking maybe😅
Also explain what is eddy current and how heat is generated
Thanks for making this video. Please make video on induction cookware
Excellent.
Greetings from Romania
thanks for explan
Awesome!!. Thank you for such a simple and to the point explanation. Also, any idea why induction cookers are consuming too much of electricity?
It consumes the power because to heat faster, it needs to create huge Eddy current. To generate that Eddy current the coil needs produce huge alternating magnetic field by passing huge current through the coil, and that's the power consumption. But it has got much higher conversion efficiency compared to other heating like IR or simple convection heating. At the end it consumes less electricity than conventional resistive heating.
Just use a gas stove
@@CUbanageNT_24 gas stoves are great to cook on, but nowhere near as efficient in the way they use the energy & impart most of their output heat into the surrounding area, not the actual pan, camp cooking is a good example of this as a small breeze can carry most of the heat away from a flame based cooker, where induction cookers impart most of their heat generated through the metallic base into the items being cooked. Another good example of power savings would be where you are cooking in an air conditioned area in hot weather, gas will impart 10 times more heat into the surrounding area to get the pan to the required heat for cooking, which then has to be removed by the A/Con’s heat pump and if you have PV solar, using an induction cooker will make a considerable difference to overall power usage in this scenario.
I dont think induction cookers actually use too much electricity, while they do use a fair bit, they are still more efficient than using a resistive element to cook with, or gas.
@@evil17 Exactly. Very well explained, being Physics guy I appreciate your both the comments. 👏
Could you make a video on discovery of proton and neutron ,please
👍👍👍👌
How much is the least distance between the induction coil and utensil?
0:19 все хорошо, но разве в Америке правило правовой руки ( оно же буравчика ) отменили? Направление тока и магнитного тока как относятся??
Cool explanation, thanks!
Good Job bro
Is that it shocks ?
So is this instrument 100% efficient as the waste product is also heat.
Can I use this video in Hindi version for my audience
Stunning rendenders and explanations
I first time heard someone say the word "lac"on TH-cam in my entire life.
I use it daily.
what program did you use to create this animation?
Wanna know too
Same question ❓
Microsoft paint 🎨
@@SauravC108 😂😂😂😂
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. :)
