A 1.10-m-long metal bar is pulled to the right at a steady 4.0 m/s perpendicular to a uniform, 0.790-T magnetic field. The bar rides on parallel metal rails connected through R = 25.5-Ω, as shown in the figure (Figure 1), 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.
