A metal ring is held horizontally and bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet is
A
more than 
or
or
B
equal to 
C
less than 
D
either
Text Solution
Verified by ExpertsThe correct answer is:
C
When the magnet is dropped through the ring, an induced current is developed into the ring in the direction opposing the motion of magnet (Lenz’s law). Therefore this induced current decreases the acceleration of bar magnet.
