(i)
As a bar magnet is pushed into the coil, a momentary deflection is observed in the galvanometer indicating the production of a momentary current in the coil.
(ii)
When the bar magnet is held stationary inside the coil, there is no deflection in galvanometer indicating that no current is produced in the coil.
(iii)
When the bar magnet is withdrawn (or pulled out) from the coil, the deflection of galvanometer is in opposite direction showing the production of an opposite current.
