Magnetic field due to currentHard
Question
The north pole of a magnet is brought near a metallic ring. Then the direction of the induced current in the ring will be:
Options
A.Towards north
B.Towards south
C.Anticlockwise
D.Clockwise
Solution

When we bring a north pole a meteallic ring applying lenz’s law the ring will behave as north pole so that repulsion occurs. So direction of current induced in it will be anticlockwise as depicted above.
