The following are the several approaches to produce a current in a coil:
An electric current is induced in a coil when it is rapidly moved between the two poles of a horseshoe magnet.
An electric current is induced when a magnet is shifted relative to a coil.
The current in the coil may be generated by keeping it fixed and rotating a magnet within it.
A steady alteration of the current in 'another coil' kept near it in a coil might create the current...
