Question

Quizplus · Accepted Answer

According to Lenz's Law, the induced current will flow in a direction that opposes the change in magnetic flux. As the north pole of the magnet approaches, the magnetic flux through the loop increases, and the induced current will be counterclockwise to create a magnetic field opposing the approaching north pole.
