The expt. arrangement consists of coil containing ‘n’ no of turns. The free end of the coil is connected to sensitive galvanometer.
(i) When a magnet is at rest, no deflection in the galvanometer.
(ii) When a north pole of magnet is moving towards the coil the galvanometers shown definition in one direction. Parallelly when a north pole of the magnet is moving away from the coil the galvanometer shows deflection in opposite direction.
(iii) The deflection of the galvanometer is large, when magnet is moving towards the coil (or) away from the coil.
From the expt it is clear that if there is a relative motion between the magnet coil, an emf is induced across the coil & induced current flows in the coil.
