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 passing through the ring is

When the magnet is allowed to fall vertically along the axis of the loop with its north pole towards the ring. The upper face of the ring will become the north pole in an attempt to oppose the approaching north pole of the magnet. Therefore the acceleration in the magnet is less than g.
