1) A metal ring is held horizontally and the bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet A) is equal to g B) is less than g C) is more than g D) depends on the diameter of ring and length of magnet Answer: Option BExplanation:As the magnet falls, the magnetic flux linked with the ring increases. This induces emf in the ring which opposes the motion of the falling magnet, so a < g
