A circular loop of wire is in the plane of the paper. The north pole of a bar magnet is being moved toward the center of the loop from a position in front of the paper. The direction of the induced current in the loop:______.
a) is north.b) is south.c) is counterclockwise.d) is clockwise.d) cannot be determined.

Answer:

counterclockwise

Explanation:

By applying Lenz's Law, as the North pole of the magnet approaches the center of the loop, the inducing magnetic flux through the loop is increasing., and therefore, the induced flux will be in the direction opposite to the magnetic field B of the magnet. Such will cause a counterclockwise current in the loop, using the right hand rule.
