Explain different ways to induce current in a coil.

Explanation

To induce current in a coil, the magnetic flux linked with it is to be changed. This is achieved if :
(a) there is a relative motion between the coil and a magnet.
(b) there is a relative motion between the coil and a conductor carrying current.
(c) there is a change in the current in a conductor placed near the coil.
