Question

15. 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(ii) withdrawn from inside the coil,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:

the answer is iii because

Explanation:

when a bar magnet is held stationary inside the coil then no cuurent is included thats why galvanometer will show no deflection

Answer 2

$\huge\underline\mathfrak\pink{Answer}$

(i) when magnet is pushed near a bar magnet then it induces current due to electromagnetic induction.

(ii) When the bar magnet is withdrawn from inside the coil of the insulated copper wire again the current is induced in the coil but this time it is in reverse direction.

(iii) When a bar magnet is held stationary inside the coil then no current is induced that’s why galvanometer will show no deflection.
