The figure shows a rod of length L = 14.5 cm that is forced to move at constant speed v = 5.06 m/s along horizontal rails. The rod, rails, and connecting strip at the right form a conducting loop. The rod has resistance 0.527 2; the rest of the loop has negligible resistance. A current i = 103 A through the long straight wire at distance a = 9.75 mm from the loop sets up a (nonuniform) magnetic field throughout...
