May one use an induction stove-top on Yom Tov?
I assume there's a fundamental difference if the pot is already on the stove before Yom Tov, and food is just poured inside; this should be permitted. But what about placing the pot on the stove? Is there any difference if the induction mechanism pauses if no pot is detected?
How induction works:
Wikipedia: Induction cooking heats a cooking vessel by magnetic induction, instead of by thermal conduction from a flame, or an electrical heating element. Because inductive heating directly heats the vessel, very rapid increases in temperature can be achieved.
Simplified [my understanding, maybe I'm wrong], every solid consists of fixed atoms with rotating electrons. Some electrons rotate clockwise and some counter-clockwise. The "rotation direction" [edit me, for the correct term], can be changed temporarily with a magnetic force. The north (N) magnetic field spins it in one direction, while south (S) spins it in the other direction.
The idea of induction, is, rapidly change between N and S causing rapid changes in the atomic particles; in turn causing massive friction, which emits heat.
