A bar magnet is dropped, N pole down, so it falls through a horizontal loop of wire. As it leaves the loop, the induced current (viewed from above) is:
A) clockwise
B) counterclockwise
C) zero

Question

Quizplus · Accepted Answer

As the N pole of the magnet leaves the loop, the magnetic flux through the loop decreases. According to Lenz's Law, the induced current will flow in a direction that opposes this change, creating a magnetic field that tries to maintain the original flux. This results in a clockwise current when viewed from above.
