Question

a coil of insulated copper wire is connected to a galvanometer what would happen if a strong bar magnet is
(a) pushed into the coil?
(b) withdrawn from inside the coil?
(c) held stationary inside the coil? ​

Answer 1

(a) deflection in galvanometer relative motion

(b) deflection in galvanometer relative motion

(c) No deflection

Answer 2

hi friends..........

ur answer is........

A Coil of insulated copper wire is connected to a galvanometer. ... (a) When the bar magnet is pushed into the coil,or(b) withdrawn from the coil, there will be a deflection in the galvanometer. This is because of the induced current in the coil which is generated due to the relative motion between the coil and magnet.

(c) When a bar magnet is held stationary inside the coil; then no current is induced that's why galvanometer will show no deflection
