The induced magnetic field attempts to bolster thedecreasing field and points down. Whenthe magnet is below the ring, its magnetic field still points down through the ring butis decreasing as the magnet falls. The induced current in thering is as shown in the drawing at the right, andthen the ring looks like a magnet with its northpole at the top, repelling the north pole of thefalling magnet and retarding its motion. The inducedmagnetic field attempts to reduce the increasingfield and points up. (a) When the magnet is above the ring its magneticfield points down through the ring and isincreasing as the magnet falls.
