Q. 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 bePhysics Question Image

Electromagnetic Induction

Solution:

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.
