Vedclass · Answer

(A) According to Lenz's law,the induced current in the coil always opposes the change in magnetic flux that produces it.When the north pole of the magnet is pushed towards the coil,the magnetic flux through the coil increases,and the induced current flows in a direction to oppose this increase.When the magnet is pulled away from the coil,the magnetic flux through the coil decreases. To oppose this decrease,the induced current flows in the opposite direction compared to the first case.Since the galvanometer pointer deflected towards $X$ when the magnet was pushed in,it will deflect in the opposite direction,i.e.,towards $X^1$,when the magnet is pulled away.

When a bar magnet is pushed towards the coil,along its axis,as shown in the figure,the galvanometer pointer deflects towards $X$. When this magnet is pulled away from the coil,the galvanometer pointer:
