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!

Q4 A bar magnet is held above a loop of wire in a horizontal plane, as shown in Figure. According to the Lenz's law (write the Lenz's law), find the direction of the induced current through the resistor (a) while the magnet is falling toward the loop and (b) after the magnet has passed through the loop and moves away from it (draw the magnetic field lines of both the magnet and loop).

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...
