Question

In an experiment, a magnet with its mangetic moment along the axis of a circular coil and directed towards the coil, is withdrawn away from the coil and parallel to itself. The current in the coil, as seen by the withdrawing magnet, is :–

(a) zero

(b) clockwise

(c) anticlockwise

(d) first (a) then (b)

Answer 1

Correct option**(b) clockwise**

Explanation:

As magnet is withdrawn from the coil, field into the coil decreases. To increase this field, current induced in the coil must be clockwise as seen by the withdrawing magnet.
