A coil is connected to a galvanometer.

Hi, I have a question and I hope anyone could answer it:

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.

1. ## A coil is connected to a galvanometer. When the N-pole of magnet is pushed into the coil, the galvanometer deflected to the right when the N-pole is removed from the coil.

Explanation:

(a) The galvanometer deflects to the left when the N-pole is removed from the coil.

(b) The galvanometer deflects to the left when the S-pole is inserted into the coil.

(c) There would no deflection in the galvanometer .i.e., it will absorb when the magnet is at rest in the coil.

Three ways for increasing the deflection on the galvanometer:

i) By increasing the number of turns in the coil .

ii) Using a stronger magnet.

iii) Increasing the speed with which magnet is pushed into the coil.
