Question

A coil of insulated wire is connected to a galvanometer. Explain what happens if a bar magnet with it's north pole towards one face of coil is: (1) moved quickly towards the coil (2)kept stationary inside the coil,and (3)moved quick away from the coil?

Answer 1

the answer is first option that is moved quickly toward the coil

Answer 2

(1). Current will be induced in coil which can be seen deflection in galvometer

(2). No current will be induced hence there is no deflection occurs.

(3). Current will induced in opp. direction... Hence deflection in galvometer pointer will also become in opp. direction....

I hope it will helpful to u..
