Exercise 29.28 Constants Part A A 1.15-m-long metal bar is pulled to the right at a steady 6.0 m/s perpendicular to a uniform, 0.765-T magnetic field. The bar rides on parallel metal rails connected through R-24.5-2, 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. Calculate the magnitude of the emf induced in the circuit Express your answer using two significant figures. Request Answer...
