6. A coil with 200 turns of wire and an area of 0.025 m is initially in a position so that its face is perpendicular to a magnetic field that has a magnitude of 0.40 T, as illustrated in Figure 1. If the coil is rotated 90 to a position with its face parallel to the magnetic field in a time interval of 0.20 s, as illustrated in Figure 2, what is the averge emf induced in the coil?
