A pair of conducting, parallel, frictionless rails is mounted on an insulating platform. The distance between the rails is L = 0.20 m. The rails are connected on one end by a R = 10 12 resistor. A conducting bar of mass 1.2 kg can slide on the rails without friction. When the conducting bar is at x = 0, the enclosed area of the loop is 0.03 m^2. There is zero resistance in the conducting bar or rails. A uniform magnetic field of 1.25 T is normal to the loop and pointing out of the page. At t = 0, the conducting bar at x = 0 is pulled at constant velocity along the rails to the right at a speed of 20.0 m/s. Required:
a. Sketch the direction of the induced current.
b. Find the magnitude of the induced current.
c. Calculate the potential (voltage) across the resistor.
