Vedclass · Answer

(D) When the metallic ring swings through the magnetic field,the magnetic flux linked with the ring changes. According to Faraday's law of electromagnetic induction,an electromotive force $(EMF)$ is induced in the ring. Since the ring is metallic,this $EMF$ causes eddy currents to flow through it. According to Lenz's law,these eddy currents oppose the motion that produced them. This magnetic damping force acts against the motion of the pendulum,causing the mechanical energy of the pendulum to dissipate as heat due to the electrical resistance of the ring. Consequently,the pendulum will come 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
