A bar magnet is dropped vertically down through a wire loop held horizontally. The magnet will fall\

Question

Professor PC Thomas Classes · Answer

\ As the magnetic passes through the coil, the flux changes. An emf is induced in it. If the coil is closed, the emf will send a current which by Lenz's law opposes the cause namely the magnet falling. So the acceleration a is les than $g$. Further it is variable acceleration.\
