Question

hey isnt it possible when to get electricity by getting an iron bar and coiling it in copper wire, then spining the iron bar to make electricity.
if there are other ways plz tell me, and if you know tell me how a windmeal works

Answer 1

it is not enough to get changing magnetic field, it also need to be perpendicular to the cross section of the coil

Answer 2

No you need a moving or changing magnetic field, not an iron bar.
