a conducting rod is moved to the right on a U- shaped conductor in a uniform magnetic field. Suppose that the length of the moving rod is l = 0.2 m, its speed is v + 0.1 m/s, the magnetic field strength is B = 1.0T (directed into the page) and the resistance of the circuit is R = 0.0200. (a) Determine the direction of induced current. (a) Calculate the induced emf of the circuit. (b) Find the magnitude and direction of the induced current of the circuit. (c) Calculate the external power is needed to move the rod at constant velocity
