Chapter 22.2, Problem 2aTH

Five loops of copper wire of same gauge (cross−sectional area). Loops 1−4 are identical; loop
5 has the same height as the others but is longer. At the instant shown, all the loops are moving at the same speed in the directions indicated.

There is a uniform magnetic field pointing out of the page in region I; in region II there is no magnetic field. Ignore any interactions between the loops.

a. For any loop that has an induced current, indicate the direction of that current.
