A bar magnet falls from height 'h' through a metal ring as shown in the figure. Will its acceleration be equal to 'g'? Give reason for your answer.

Text Solution

Verified by Experts


The acceleration of the falling magnet will be less than .g. As the magnet falls, the magnetic flux linked with the metal ring increases. The induced current in the ring opposes the downward motion of the magnet.
