A metalic ring is attached with the wall of a room. When the north pole of a magnet is brought near to it, the induced current in the ring will be

A

anti-clockwise

B

clockwise

C

first anti-clockwise and then clockwise

D

first clock wise and then anti-clockwise

Text Solution

Verified by Experts

The correct Answer is:
A

The magnet gets repelled. Therefore, north pole is formed on the top side and hence current will flow in anti-clockwise direction.
