1.

A rectangular loop of wire with sides 0.142 and 0.528 m lies in a plane perpendicular to a constant magnetic field (see part a of the drawing). The magnetic field has a magnitude of 0.604 T and is directed parallel to the normal of the loop's surface. In a time of 0.104 s, one-half of the loop is then folded back onto the other half, as indicated in part b of the drawing. Determine the magnitude of the average emf induced in the loop.

2. Two flat surfaces are exposed to a uniform, horizontal magnetic field of magnitude 0.39 T. When viewed edge-on, the first surface is tilted at an angle of 25° from the horizontal, and a net magnetic flux of 8.4 x 10-4 Wb passes through it. The same net magnetic flux passes through the second surface. (a) Determine the area of the first surface. (b) Find the smallest possible value of the area of the second surface.
