If a bar magnet is falling through a loop of wire, the induced current in the loop of wire sets up a field which exerts a force on the magnet. This force between the magnet and the loop will be repulsive when: A. the magnet enters the loop B. the magnet is halfway through C. the magnet is leaving the loop D. never Please provide an explanation!

Physics question.
Suppose that a bar magnet falls through a conducting hoop of wire with its north pole facting downward. Three consecutive snapshots of its descent are shown below. For each snapshot, state whether: the magnetic flux through the loop is upward, downward, or zero; the induced current is clockwise, counterclockwise, or zero, from the point of view of an observer looking down from above the loop. Make a qualitative sketch of the induced current versus time (taking counterclockwise as...

A bar magnet is released from rest some height above the center of a loop wire standing flat on a table, as shown in the figure below. The wire has no net charge and no initial current is flowing in it. The magnitude of the acceleration of the falling magnet will be O slightly larger than 9.8 m/s2 much larger than 9.8 m/s2 exactly 9.8 m/s2 exactly 4.9 m/s2 smaller than 9.8 m/s2 S N
