A coil of insulated copper wire is connected to a galvanometer. What will happen if a bar magnet is

(i) pushed into the coil,

(ii) withdrawn from inside the coil,

(iii) held stationary inside the coil?

Solution :-

(i) When a bar magnet is pushed into the coil, current is induced in the coil momentarily, as a result the galvanometer deflects in a particular direction momentarily.

(ii) When the bar magnet is withdrawn from inside the coil, current is induced momentarily but in the opposite direction and the galvanometer deflects in the opposite direction momentarily.

(iii) When the bar magnet is held stationary inside the coil, no current will be induced, as a result there will be no deflection in the galvanometer.
