14. A metal rod PQ is part of a closed circuit and moves through a uniform magnetic field as shown in the figure below. The rod is pushed to the left at a constant speed. What, if any, is the direction of the current induced in the rod? Bout of page Р R A. From P to Q B. C. From Q to P Depends on whether the rod is accelerating or decelerating There is no current induced in rod D.

15. The figure shows a bar magnet moving vertically upward toward a horizontal coil. The poles of the bar magnets are labeled X and Y. As the bar magnet approaches the coil it induces an electric current in the direction indicated on the figure (counter- clockwise as viewed from above). What are the correct polarities of the magnet? 1 A B. X is a south pole, Y is a north pole X is a north pole, Y is a south pole Both X and Y are north poles Both X and Y are south poles C. D.

13. A bar magnet is falling through a loop of wire with constant velocity. The south pole enters first. As the magnet leaves the loop, the induced current (as viewed from above) is: A. zero B. clockwise C. counterclockwise D. along the length of the magnet
