coil wont generate electricity 2?
hey guys got a question
i mad a coil and ive just tested its resistance when i touched the enamel its 0 so i know that its insulated and when i touch the stuff i scraped of its 2.4 so i know that im connected but when i pass a magnet through it no volts are shown not even 1 millivolt and im passing a rare earth magnet through 30 coils any ideas why this isnt working is 2.4 bad? i got 2.4 when i put it on 200
thanks for reading me question

do two opposing magnets have any "friction" or resistance to movement?

do two opposing magnets have any "friction" or resistance to movement?
if I have two opposing magnets and I rotate / move one of them relative to the other, is there any friction?
would there be any eddy currents if it was an alnico or neodymium magnet?
a ferrite magnet wouldn’t have any eddy currents
ASSUME THAT BOTH MAGNETS ARE CONSTRAINED SUCH THAT THEY WILL NOT “SLIDE” OFF ONE ANOTHER OR FLIP OVER!
I know about air resistance!
