Vedclass · Answer

(D) When the metallic ring moves through the magnetic field,the magnetic flux linked with the ring changes.According to Faraday's law of electromagnetic induction,an induced electromotive force $(EMF)$ is produced in the ring.Since the ring is metallic,it has some resistance,which leads to the flow of induced eddy currents.According to Lenz's law,these eddy currents oppose the motion that causes them.This results in a damping force acting on the pendulum,which dissipates the mechanical energy of the pendulum as heat.Consequently,the amplitude of oscillation decreases rapidly,and the pendulum comes to rest very soon.

$A$ metallic ring connected to a rod oscillates freely like a pendulum. If now a magnetic field is applied in a horizontal direction so that the pendulum now swings through the field,the pendulum will
