DIY induction stove – Frying eggs with magnets

The easter egg that I love is the actual, physical reference to the Spaceballs movie.<p><a href="https:&#x2F;&#x2F;cdn.instructables.com&#x2F;ORIG&#x2F;FYX&#x2F;9FR4&#x2F;JNULHKMJ&#x2F;FYX9FR4JNULHKMJ.jpg" rel="nofollow">https:&#x2F;&#x2F;cdn.instructables.com&#x2F;ORIG&#x2F;FYX&#x2F;9FR4&#x2F;JNULHKMJ&#x2F;FYX9FR4...</a>

As I have seen an induction furnace very quickly melt an aluminum billet, and this device works on an aluminum pan, it is not clear to me why induction stoves do not work on aluminum pans - is it because stoves work at a frequency that depends on magnetic hysteresis losses in ferromagnetic materials for generating most of the heat? Is it likely that this device would work better on an iron or steel pan than the aluminum one used?

Neat! <a href="https:&#x2F;&#x2F;youtu.be&#x2F;pCON4zfMzjU" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;pCON4zfMzjU</a> seems to use the same principle for levitation.

Good thing it doesn&#x27;t produce more heat, their Lexan sheet would start getting very soft above 150C!

This is an interesting alternative to residential induction stoves that use AC to create the magnetic fields.<p>I wonder what the power usage difference is. This style of heating up the metal instead of using AC current to generate electromagnetic fields could be better for &quot;off-grid&quot; scenarios.

K&amp;J Magnetics gave it a try: <a href="https:&#x2F;&#x2F;www.kjmagnetics.com&#x2F;blog.asp?p=induction-stove" rel="nofollow">https:&#x2F;&#x2F;www.kjmagnetics.com&#x2F;blog.asp?p=induction-stove</a>

Isn&#x27;t this leaving a lot of magnetic field on the table (literally) where you could improve by directing the fields more into the pan and closing the spacing to the pan significantly?

Very interesting indeed! But those guys could use some cooking lesson for frying eggs... :-D

Efficiency?

I misread that as maggots. I recall reading that the heat generated by a mass of maggots causes them to break out in to smaller groups. So my initial thought was whether someone had figured out how to fry an egg by harnessing that heat. <a href="https:&#x2F;&#x2F;www.wired.com&#x2F;2014&#x2F;04&#x2F;maggots-bring-the-heat&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.wired.com&#x2F;2014&#x2F;04&#x2F;maggots-bring-the-heat&#x2F;</a>

This is a failed experiment that was posted.
