The diagram below show 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. Does the direction of the current in the coil appear clockwise or anticlockwise viewed from this end $A$ ?

The direction of induced current at end $A$ is anti-clockwise.
The direction of induced current at end $A$ is clockwise.
The direction of induced current at end $A$ cannot be determined.
The direction of induced current at end $A$ is first clockwise and then anticlockwise.

By lenz-apos-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 as seen from end A will appear as a north pole- This appears when anticlockwise current -as seen from end A- is induced in the coil-

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 as seen from end A will appear as a north pole. This appears when anticlockwise current (as seen from end A) is induced in the coil.
