Will an induction cooker work in reverse if a hot pan is place on the coil?

AI Thread Summary
An induction cooker does not work in reverse when a hot pan is placed on the coil, as it relies on electromagnetic induction to generate heat. The heat from the pan primarily transfers to the coil through conduction, not induction. A hot object does not produce the necessary magnetic field to create a current in the induction coil. Instead, it emits infrared radiation, which is not effective for induction cooking. The discussion concludes that while it would be interesting if it worked, it does not.

I was wondering whether an induction hob cooker would work in reverse if a hot pan is placed on the coil - so would this generate a current? I would assume not as the heat induction pan wouldn't be able to create a magnetic field in the coil?

You are correct...the hot pan can heat the coil, mostly via conduction, but alas a hot object won't usually produce electromagnetic induction...just a little infrared radiation...
 
Yes shame it would be cool. Thanks for the response.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
