A 1.40-m-long metal bar is pulled to the right at a steady 5.9 m/s perpendicular to a uniform, 0.730-T magnetic field. The bar rides on parallel metal rails connected through R = 25.4-N, 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.
