A metal loop is held above the S pole of a bar magnet,as shown in the figure, when the magnet is suddenly dropped fromrest. Just after the magnet is dropped (before it completely passesthrough the coil), the induced current in the loop, as viewed fromabove it, is directed

(a) counterclockwise (b) clockwise (c) zero

Just after the magnet has completely passed through thecoil, the induced current in the loop, as viewed from above it, isdirected

A bar magnet is held in a vertical orientation above a loop of wire that lies in the horizontal plane as shown in Figure OQ31.7. The south end of the magnet is toward the loop. After the magnet is dropped, what is true of the induced current in the loop as viewed from above?

(a) It is clockwise as the magnet falls toward the loop.

(b) It is counterclockwise as the magnet falls toward the loop.

(c) It is clockwise after the magnet has moved through the loop and moves away from it.

(d) It is always clockwise.

(e) It is first counterclockwise as the magnet approaches the loop and then clockwise after it has passed through the loop.

4)A square loop of wire lies in the plane of the page. A decreasing magnetic field is directed into the page. The induced current in the loop is: a. counterclockwise b. clockwise c. zero d. depends upon whether or not B is decreasing at a constant rate e. clockwise in two of the loop sides and counterclockwise in the other two 5) A vertical bar magnet is moved at constant velocity through the center of a horizontal loop of wire, with its north pole leading. At the instant when the midpoint of the magnet is in the plane of the loop, the induced current in the loop, viewed from above, is: a. maximum and clockwise b. maximum and counterclockwise c. not maximum but clockwise d. not maximum but counterclockwise e. essentially zero
