How to Boil Water Using Magnets

(28 Nov 2021) I added descriptions to the video in 56 languages. --------------------------- Boiling water with magnets. New edition - https://www.youtube.com/watch?v=7wZ8DWu-sw8 For those who want to repeat the experiment. For faster heating plays the role of RPM motor and the number of magnets and the radius of the disk. More radius, more magnets, more RPM = more frequency change of the magnetic field N / S. Frequency affects the rate of heating. But if the motor is low-power and the aluminum / copper piece is large and thick, then this piece will brake the magnets and the RPM will decrease. Therefore, choose a balance - motor power & volume of water to heat. If the motor power is insufficient, you can wait a very long time. :)

A good little demo of uses of eddy currents -- although uneconomic in terms of boiling water. BUT that is the point because we use quite big motors in many things and waste the potential of eddy currents produced in the process of motors doing a 'main job'. This is not to be confused with induction appliances and you make that clear. Excellent.

I heard about the theory of this in physics class 35 years ago but this is the first time I have ever seen it. Thank you sir for your outstanding effort.

amazing, these are things we've only learned from independent media congratulations on sharing your knowledge

That is a rather interesting alternating magnetic field design there! LOL! Though likely quite inefficient it obviously is effective. Nice work. 😀

l just sat here and watched water boil, l need to get out more

Come on all you nay sayers! This is a great teaching tool for introducing new concepts to young children on magnetism .

Thank you so much for this informative video! I’m sure those who live off the grid will make good use of this principle

Outstanding my guy. Looks great 🔥

This really is amazing. You've discovered the cure for insomnia.

I met Eddy Current once, nice fellow, very misunderstood, and a little bipolar. :)

Very interesting. I’ll have to try this if I can get the magnets. Thanks for your video.

Wow, something more interesting than watching paint dry

I knew why it would heat before you started but you displayed it well. You always stir my interest in making things myself. Thanks !

gave an upvote because dude had enough attention to detail to polish the edges of the thick aluminum disc underneath the glass!

Woow , what an idea to explain eddy currents generation 👌 I will use your such idea to explain such eddy current effect to my child and also heating effect through it 👍 Thanks a lot for your great idea with such simple arrangements 🙏😀😀😀

Exactly what I knew would happen beautiful visual explanation of eddy currents in non ferrous metal

Really nice demonstration of induction heating. I enjoyed that.

Great video! Gave a very good understanding of the concept. Thanks.

Thanks! I've been wondering how induction heating was made. Fyi for people reading this: Normally one uses switching currents in a copper coil to shift the magnet fields
