A coil is connected to a galvanometer. When the N-pole of a magnet is pushed into the coil, the galvanometer deflected to the right. What deflection, if any , is observed when:
(a) the N-pole is removed ?
(b) the S-pole is inserted ?
(c) the magnet is at rest in the coil ?
State three ways of increasing the deflection on the galvanometer.

Answer

N/a

Explanation

(a) The galvanometer is deflected to the left
(b) The galvanometer is deflected to the left
(c) No deflection in galvanometer , Increase the number of turns in the coil , Use a stronger magnet , Increase the speed with Which magnet is pushed into the coid (or removed)
