A magnet is allowed to fall through a metal ring. During the fall:

The correct answer is: Its acceleration is lesser than g

When a magnet is allowed to fall through a metal ring, its acceleration is lesser than g.

• The magnet creates a strong magnetic field with a metal ring.
• When the magnet is allowed to pass through a metal ring, the speed of the magnet becomes relatively less.
• The flux associated with the metallic ring changes as the magnet falls through it, producing an EMF.
• This produced emf fights against the magnet's driving force. i.e. it forces the magnet to point upward.
• As it creates a magnetic field, the acceleration magnet therefore becomes lesser than g.
