 Which of the following examples represent periodic motion?

(b) A freely suspended bar magnet displaced from its N-S direction and released.

Answer

The motion of a freely suspended magnet, if displaced from its North-South direction is released, then the motion is periodic. This is because the magnet oscillates about its position with a definite period of time.
