A copper ring is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet while it is approaching the ring is

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. Hence, he acceleration of the falling magnet while it is approaching the ring is Less than that due to gravity.
