19. A long straight wire is parallel to one edge and is in the plane of a single-turn rectangular loop
as shown in the Figure. If the loop is moving in the plane shown so that the distance y changes
at a constant rate of 20 cm/s, what is the magnitude of the emf induced in the loop at the instant
y = 5.0 cm? Let I= 50 A, a = 50 cm, b = 6 cm.
