Question

A coil of insulated wire is connected to a galvanometer. Explain what happens if a bar magnet with its
north pole towards one face of the coil is: (Refer C.M Pg 135 0:13)
3M
D) moved quickly towrds
ii) kept stationary inside the coil, and
ili) moved quick away from the coil​

Answer 1

Answer:

Theory: Induction of electric current.

Explanation:

I. When the magnet is moved quickly towards the coil, there will a momentary deflection of the galvano meter either to one side (say to north).

2.No change in the galvanometer.

3. There will be a momentary deflection to the other side (say south).

All these changes happen due to the induction of electric current.
