The North pole of a magnet is falling on a metallic ring as shown in the figure. The direction of induced current, if looked from upside in the ring will be

A

anti-clockwise

B

clockwise

C

clockwise or anti-clockwise depending on radius of the ring

D

no induced current

Text Solution

Verified by Experts

The correct Answer is:
A

As north pole approaches the ring, flux through ring increases. From Lenz.s law magnetic field produced by ring should oppose this change. This happens when current in it flows anti-clockwise direction.
