Physics Motion in a Straight Line MHT CET 2026

A bar magnet falls from a height 'h' through a metal pipe its acceleration after coming out of pipe is

(A)less than 9.8 m/s
(B)greater than 9.8 m/s
(C)equal to 9.8 m/sCorrect
(D)equal to 'h' m/s

Answer: (C)

Solution

While the magnet falls inside the metal pipe, the changing flux induces eddy currents in the pipe, and by Lenz's law their magnetic field opposes the motion, so the acceleration inside is less than (the magnet quickly reaches a terminal speed). Once the magnet comes out of the pipe, no conductor is
