Vedclass · Answer

(C) When a bar magnet falls through a metal pipe, the changing magnetic flux through the pipe induces eddy currents in the pipe material.According to Lenz's Law, these eddy currents create a magnetic field that opposes the motion of the falling magnet, resulting in a retarding force.However, once the magnet exits the metal pipe, there is no longer any change in magnetic flux associated with the pipe.Consequently, no eddy currents are induced, and the retarding force vanishes.The only force acting on the magnet is gravity.Therefore, the magnet falls freely under the influence of gravity alone, and its acceleration becomes equal to the acceleration due to gravity, which is $g = 9.8 	ext{ m/s}^2$.

$A$ bar magnet falls from a height $h$ through a metal pipe. Its acceleration after coming out of the pipe is:
