In the Figure to the right a conducting rod with length L = 45 cm is moving in a magnetic field of magnitude 0.55 T directed into the page as shown. The rod moves with a constant speed of 5.2 m/s in the direction shown. When the charges in the rod are in equilibrium an electric potential is induced across the length of the rod. The electric potential between the two ends of the rod (a and b) is: a. 0.884 V with a at a higher potential than b. b. 0.884 V with b at a higher potential than a. c. 1.287 V with a at a higher potential than b. d. 1.287 V with b at a higher potential than a
