A copper ring having a cut such as not to from a complete loop 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 is

A copper ring is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. Will the acceleration of the falling magnet be equal to, greater than or less than that due to gravity?

Consider metal ring kept on a horizontal plane . A bar magnet is held above the ring with its length along the axis is held above the ring with its length along the axis of the ring . If the magnet is dropped freely the acceleration of the falling magnet is : ( g is accelration due to gravity )
