Answer 1

You don’t even need a “magnet”, just a magnetic field… which can be created by running electricity through some coils of wire. And then if you move other coils of wire through the field made by the first, current will flow.

Alternatively, if you run current through the second coils of wire, it will push against the magnetic field and create movement!
