Vedclass · Answer

(C) According to the principle of electromagnetic induction,an electric current is induced in a coil only when there is a change in the magnetic flux linked with it.When a bar magnet is moved relative to the coil,the magnetic flux changes,inducing a current.However,when a bar magnet is held stationary inside the coil,the magnetic flux linked with the coil remains constant.Since there is no change in magnetic flux,no current is induced in the coil.Therefore,the galvanometer will show no deflection.

$A$ coil of insulated copper wire is connected to a galvanometer. What will happen if a bar magnet is held stationary inside the coil?
