Consider a thin rod of resistance R = 12.0 Ohm, mass m = 60.0 g and length L=20.0 cm. It is free to slide without friction on a vertical U-shaped wire. There is a uniform magnetic field of magnitude B = 1.20 T directed into the page, and the rod is stationary at t = 0 s. 5b. As the rod drops and current is induced in the rod, there is a magnetic force acting on the rod also. Find the magnitude and direction of the magnetic force on the rod (you may include vy in your answer) by going through the following steps: i. The direction of the induced current is (leftward/rightward) through the rod. ii. The direction of magnetic force FB on the rod is (upward/downward) iii. The magnitude of FB on the rod in terms of L, B, R and vy ONLY is
