A 1.50-m-long bar is pulled to the right at a steady 5.0 m/s perpendicular to a uniform 0.75 T magnetic field. The bar rides on parallel metal rails linked through a 25Ωresistor R, so the apparatus makes a complete circuit. The resistance of the bar and rails is negligibly small.

a) Decide the emf induced in the circuit.

b) Decide the magnitude and direction of the current in the circuit.

c) Decide the magnitude of the force required to move the bar.
