Answer 2

Explanation:

As the magnet falls the flux through the ring changes. Regardless whether the flux increases or decreases, by Lenz's law a current is induced in the ring that opposes the change in flux. This induced current induced a magnetic field that interacts with the falling magnet and decreases the acceleration of fall below g.
