5. (20 points) The figure shows a rod of length L = 12.0 cm that is forced to move at constant speed v = 6.00 m/s along horizontal rails. The rod, rails, and connecting strip at the right form a conducting loop. The rod has resistance 2.00 2; the rest of the loop has negligible resistance. A two long straight wires, each carrying current i = 125 A in the opposite direction at a distance a = 12.0 mm from the loop set up a magnetic field B throughout the loop. (a) What is the current induced in the loop? (b) What is the magnitude of the force that must be applied to the rod to make it move at constant speed? (c) At what rate does this force do work on the rod? (d) If the two currents move in the same direction, what is the current induced n the loop
