Question:

A single-turn rectangular loop of width W and length L moves parallel to its length with a speed v. The loop moves from a region with a magnetic field B(vector) perpendicular to the plane of the loop to a region where the magnetic field is zero, as shown in FIGURE 23-53. Find the rate of change in the magnetic flux through the loop

(a) before it enters the region of zero field,

(b) just after it enters the region of zero field, and

(d) For each of the cases considered in parts (a), (b), and (c), state whether the induced current in the loop is clockwise, counterclockwise, or zero. Explain in each case.
