A bar magnet is held stationary while a circular loop of wire is moved toward the magnet at constant velocity at position A as in the figure below. The loop passes over the magnet at position B and moves away from the magnet at position C. (For the following questions, state the directions as if you were to the right of the magnet, watching the loop of wire move away from you.) B (a) Find the direction of the induced current in the loop using Lenz's law at position A. clockwise O counterclockwise O No current is induced. (b) Find the direction of the induced current in the loop using Lenz's law at position C. O clockwise O counterclockwise No current is induced. (c) What is the induced current in the loop at position B? (Position B has the center of the loop exactly at the midpoint of the bar magnet.) O clockwise O counterclockwise O No current is induced. Explain.
