Question

26.
A conducting ring R is placed on the axis of a bar magnet M. The plane of R is perpendicular to this
axis. M can move along this axis, then
R
(1) M will repel R when it is moving towards R.
(2) M will attract R when it is moving towards R.
(3) M will repel R when moving towards as well as away from R.
(4) M will attract R when moving towards as well as away from R.​

Answer 1

Answer:

Correct Answer is: (a) M will repel R when it is moving towards R. Let the N-pole of M face R. As M moves towards R, applying Lenz’s law, clockwise current flows in R, as seen from the right of R. Hence, the face of R towards M will behave as a N-pole and repel M. A similar argument will apply to the S-pole of M facing R. Also, M will attract R when moving away from R.
