The North pole of a magnet is falling on a metallic ring as shown in the figure. The direction of induced current, if looked from upside in the ring will be

Options

A. clockwise or anti-clockwise depending on metal of the ring
B. no induced current
C. Anti-clockwise current
D. clockwiser

Answer

C

Explanation

By Lenz's law the direction of induced current in the ring is such as to oppose the falling of N-pole of the magnet. So, the direction of induced current will be anti-clockwise, because the induced current makes the ring a magnetic dipole. with its N-pole upward which opposes (repel) the N-pole of falling magnet. Hence, the direction of the current in the ring will be anti-clockwise.
