Question

The north pole of a long horizontal bar magnet is being brought closer to a vertical conducting plane along the perpendicular direction. The direction of the induced current in the conducting plane will be
(a) Horizontal(b) Vertical(c) Clockwise(d) Anticlockwise

Answer 1

In the anticlockwise direction. This can be found by Fleming's right-hand rule.

Answer 2

Answer:

C) clockwise

Explanation:

We can solve this question using Lenz's law and Fleming's right hand rule.

The north pole of a long horizontal bar magnet is being brought closer to a vertical conducting plane along the perpendicular direction.

According to the Lenz's law,

Coil will produce magnetic field around North Pole to repel incoming North Pole.

The induced emf will oppose motion of magnet.

By using the Fleming's right hand rule, the direction of induced current will be clockwise.
