Question

A metallic ring with a cut is held horizontally and a magnet is allowed to fall vertically through the ring; then the acceleration of the magnet is:

• A. equal to g
• B. less than g
• C. more than g
• D. sometimes less and sometimes more than g

Answer 1

The correct option is A equal to g

Since the metallic ring is cut, although there is a change in flux through the ring but the circuit is not completed so there can't be any current in the ring to oppose the motion of the magnet.

Thus, the acceleration of the magnet is just equal to g.
