The given figure shows a coil connected to a centre zero galvanometer G. The galvanometer shows a deflection to the right when the N-pole of a powerful magnet is moved to the right as shown.

The deflection occurs in the galvanometer because of:

The change in the magnetic flux linked with the coil induces emf / current in the coil and hence the galvanometer shows deflection

Solution

The correct option is A
The change in the magnetic flux linked with the coil induces emf / current in the coil and hence the galvanometer shows deflection

Due to motion of the magnet, there is a change in the magnetic flux linked with the coil. As a result the, emf is induced across its ends, due to which induced current flows in the coil and so galvanometer shows deflection.
