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 ² (b) greater than 9.8 m/s ² (c) equal to 9.8 m/s ² (d) equal to 'h' m/s ²

Answer: (c). Outside the pipe there is no metal around the magnet, so no eddy currents and no magnetic drag. Only gravity acts (air resistance neglected), so a = g = 9.8 m/s ². So the answer is (c).

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

Show answer and solution

Answer: (c)

Outside the pipe there is no metal around the magnet, so no eddy currents and no magnetic drag.
Only gravity acts (air resistance neglected), so $a = g = 9.8$ m/s $^2$ .
So the answer is (c).
