A metal plate is attached to the end of a rod and positioned so that it can swing into and out of a perpendicular magnetic field pointing out of the plane of the paper as shown. In position 1, the plate is just swinging into the field; in position 2, the plate is swinging out of the field. Does an induced eddy current circulate clockwise or counterclockwise in the metal plate when it is in

(a) Position 1
(b) Position 2?
(c) Will the induced eddy currents act as a braking force to stop the pendulum motion? Explain.
