a permanent bar magnet with the north pole pointing downward is dropped through a solenoid, as shown in the illustration. a bar magnet oriented vertically, with its south pole on top and its north pole on the bottom. directly below the magnet, and also aligned vertically, is a solenoid consisting of wire wound around an open tube. when viewed from above, the wire spirals around and down the tube in a clockwise fashion. to the left of the solenoid, the wire leads are connected to an ammeter, closing the circuit. what is the direction of the induced current that would be measured in the ammeter as the magnet falls completely through the solenoid?
