How does inductive heating with magnets work?
(OP)
I've been trying to learn more about inductive heating to try and answer a few questions of mine concerning the amount of heat generated by magnets passing through opposite magnetic fields at a high frequency. Does inductive heating heat from the inside of a conductive material outward, or does it heat from the surface in, like conventional methods?

The material does not need to be a magnet. Any electrically conductive material moving in a field will heat.

Your design in a previous post is similar to the rotor of an eddy current separator for municipal refuse. The eddy current separator has a number of PM's arranged like your inner cylinder. It rotates at speeds of up to say 3000 RPM. Hold an aluminum can near the rotor for a few seconds and your bare fingers WILL let go. Really neat effect.

Your rotor at 1000 rpm will require siginificant engineering to not come apart.
Think carbon fiber to minimize all of these problems.
You have come back to your earlier post where you are asking for actual design values. You need to do the work or hire someone to do it for you. Or make prototypes and probably watch a bunch fail. You should have fun either way.

For Example: stationary magnet: N
S
passing magnets: N N N N N (direction of
S S S S S motion ->)
Why wouldnt this setup act as if the passing magnets were all one continuous magnet passing by the stationary magnet? Its possible I'm just not grasping the concepts here. I trust you all know more about magnets than I, and if you say this will still generate heat then I'll believe you. Magnets are not my specialty.
