The diagram shows a coil connected to a centre zero galvanometer G . The galvanometer shows a deflection to the right. Does the direction of current in the coil appear clockwise or anticlockwise when viewed from the end A .

By Lenz's law, the direction of induced current will be such that it will oppose the motion of magnet towards the coil. By this logic, the coil, A will appear as a north pole and b appears as south pole. Hence, the induced current direction in the coil is anticlockwise as seen from end A.

The diagram shows a coil connected to a centre zero galvanometer G . The galvanometer shows a deflection to the right. State the observation in G when both the coil and the magnet are moved to the right at the same speed.

When both the coil and the magnet are moved to the right at the same speed, the galvanometer shows zero deflection. This is because, there is no relative motion between the coil and magnet and no change in magnetic flux.
