13. You have the apparatus shown in Figure P21.13. A circular metal plate swings past the north pole of a permanent magnet. The metal consists of a series of rings of in- creasing radius. Indicate the direction of the current in one ring (a) as the metal swings down from the left into the magnet- ic field and (b) as the metal swings up to- ward the right out of the magnetic field. Use Lenz's law to justify your answers. Figure P21.13 Metal plate Magnet N
