ElectroMagnetic InductionHard
Question
A bar magnet is released from rest coaxially along the axis of a very long, vertical copper tube. After some time the magnet
Options
A.will move with an acceleration g
B.will move with almost constant speed
C.will stop in the tube
D.will oscillate
Solution
Since the tube is very long the force on magnet due to induced current will continue to oppose its motion till it acquires a constant speed.
