Question

When a magnet moves away from the loop as shown in the figure, the direction of induced current as seen from the magnet's side is

• A. Clockwise
• B. First clockwise then anticlockwise
• C. Anti-clockwise
• D. First anti-clockwise then clockwise

Answer 1

The correct option is C Anti-clockwise

As the magnet moves away, then according to Lenz’s law a current will be induced in the magnetic field so as to oppose the movement of the magnet. Therefore, a north pole will be developed on the face of the loop facing the magnet and therefore from fleming’s right hand rule an anti-clockwise current will be developed.
