Question

A coil of insulated copper wire is connected to a galvanometer. What will

Happen to the galvanometer if a bar magnet is

(i) pushed into the coil,

(ii) withdrawn from inside the coil,

(iii) held stationary inside the coil? ​

Answer 1

Answer:

1.) If the magnet is pushed into the coil, it will start to deflect.

2.) If the magnet is withdrawn from inside the coil, galvanometer will deflect and will become stationary after a second,as the magnet moves/withdrawn.

3.) If the magnet is held stationary,the point of galvanometer will rise and will become stationary at the same position.

Explanation:

Because, when a magnet is moved through or is taken nearer to a insulated copper, due to magnetic field of the magnet a specific type of current is produced in the wire which deflects the point of galvanometer.
