Chapter 29, Problem 29.16E

The current I in a long, straight wire is constant and is directed toward the right as in Fig. E29.16. Conducting loops A, B, C, and D are moving, in the directions shown, near the wire, (a) For each loop, is the direction of the induced current clockwise or counterclockwise, or is the induced current zero? (b) For each loop, what is the direction of the net force that the wire exerts on the loop? Give your reasoning for each answer.
