stationary with respect to the magnet.

(a) It deflects towards right.

(b) It deflects towards left.

(c) It deflection drops to zero.

(d) It first moves to the right and then to the left.

4. What happen to the needle of the galvanometer, when the north pole of the bar

magnet is withdrawn away from the coil.

(a) It deflects towards right.

(b) It deflects towards left.

(c) It deflection drops to zero.

(d) It first moves to the right and then to the left.​
