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!

A bar magnet is moved (in the plane of the page) with respect to a single-tur of radius 5.00 cm as shown (the coil lies in a plane perpendicular to the di of the bar magnet). Over a time interval of 0.150 s, the magnitude of the magnetic field at the coil varies from 0.640 T to 0.240 T. The resistance of coil is 2.50 Ohms. Assume that the magnetic field is uniform over the bounded by the coil. 4....
