If a copper ring is moved quickly towards south pole of a powerful stationary bar magnet, then

Options

A. current flows through the copper ring
B. voltage in the magnet increases
C. current flows in the magnet
D. copper ring will get magnetised

Answer

A

Explanation

When a copper ring is moved in a magneti field, an induced electromotive force is produced due to change of flux. Hence, the current flows through the copper ring.
