In the sketch below, the two shaded regions have uniform magnetic fields directed out of the page. The magnitude of the field in the left region is B1 = 6.4 T, and the magnitude of the field in the right region is B2 = 0.5 T. Four identical square loops of wire are shown with arrows indicating their velocities. Each side of the loop has a length of L = 0.25 m. The value inside each arrow gives the magnitude of the velocity. The speeds are all multiples of v = 0.47 m/s. For the instant illustrated, find the magnitude and direction (clockwise or counterclockwise) of the induced emfs in each of the four wires: EA, EB, EC, and ED.
