Question

Quizplus · Accepted Answer

As the north pole of the bar magnet falls through the loop, a clockwise current is induced in the loop, according to Lenz's law. When the magnet reaches the center of the loop, the magnetic field around it starts to decrease, and so the induced current reverses direction and flows counter clockwise. Therefore, the current flows first in a counter clockwise direction, then in a clockwise direction, making option D the correct answer.
