A rectangular loop of wire with sides 0.261 and 0.581 m lies in a plane perpendicular to a constant magnetic field (see part a of the drawing). The magnetic field has a magnitude of 0.750 T and is directed parallel to the normal of the loop's surface. In a time of 0.181 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.
