A metal bar with length = 1.50 m is pulled to the right at a steady speed |v| = 5.0 m/s perpendicular to a uniform magnetic field with magnitude 0.750 T. The bar rides on parallel metal rails connected through a resistor with resistance 25.002, as shown in Figure below, so the apparatus makes a complete circuit. You can ignore the resistance of the bar and the rails. a) Calculate the magnitude of the emf induced in the circuit. b) Find the direction of the current induced in the circuit. c) Calculate the current through the resistor.
