I have some really powerful neodymium magnets lying around, as well as some 30 AWG copper magnet wire. I needed some magnets for cabinets and mounting things, so I decided to get a few extra.
Obviously you could wind a wire many times in the same direction around a ferrite core (a bolt or something) to get a decent inductance. But what if you used a neodymium magnet as the core? What would it's inductance look like? How would it behave in pure DC, PWMed, and AC circuits? And what different ways could you wind it to get the maximum inductance or achieve other effects? I understand the basics of inductors in circuits (inductive reactance, series/parralel, phase shift, LC/resonance etc.) but do not know too much about how different cores affect them.
I even have a few of these. I imaging with such strong magnetic fields you could get very large inductances.
