get a choclate bar melt it place in a magnet shaped mold with bits of steel in it and cook and freeze
A spinning magnet inside a coil of copper wire will produce electricity.
It is weird
no
heated or dropped on a hard surface
Yes.
magnet produce emf it maintain the resistance as same
Well, Many things can produce electricity. An easy way to produce electricity is to get a coil and pass a bar magnet through it.

Faraday found that a wire passed by a magnet induces a current in the wire. This led to making an electrical generator.

The shape of the magnet is unimportant. Any moving magnet can induce a voltage in a wire. Or any changing magnetic field. If the magnet rotates, its magnetic field will change, so yes.
