The more is the velocity of magnet falling freely in the copper pipe, the more is the strength of the induced current as it opposes strongly the change in associated magnetic flux. At a time t, the strength of the induced eddy current is such that it balances out the weight of the magnet.

At that instant of time, the magnet attains its terminal velocity and the acceleration of the magnet becomes zero. So, the magnet will move with its constant terminal velocity.

It is seen that, if a permanent magnet is dropped down a vertical copper pipe, it eventually attains a terminal velocity, even if there is no air resistance. Explain the phenomenon.
