Question

A solid copper pendulum is made to oscillate in a region of uniform magnetic field that is perpendicular to its plane of oscillation. Due to the presence of the magnetic field, the pendulum will:

Professor PC Thomas Classes · Answer

(c) : As the copper pendulum swings into and out of the magnetic field, the magnetic flux passing through it changes. This induces swirling eddy currents within the bulk of the copper. According to Lenz's law, these eddy currents create magnetic fields that oppose the relative motion of the pendulum. This results in heavy electromagnetic damping, causing it to come to rest much faster.
