Conceptual: A conducting loop of wire is oriented horizontally, and a magnet is falling downward, through the loop. (a) Draw the direction of the induced current that flows in the loop as the magnet falls downward. (b) Sketch and label the magnetic field lines that are created by the induced current in the loop. (c) Does this create an attractive or repulsive force between the loop and magnet?

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 square loop made of copper wire is falling (moving downward
due to gravity) out of a region where there is a constant magnetic
field of magnitude Bext = 0.235 T. The magnetic field is
perpendicular to the plane of the loop, either into or out of the
page (it doesn't matter which direction).
The loop is falling with a constant
velocity because of the current induced in the loop
and the magnetic field.
What is the velocity of the...
