22. assignment (induced emf-metal bar)

A 2.00-m-long metal bar is pulled to the right at a steady 4.7m/s perpendicular to a uniform, 0.770-T magnetic field. The bar rides on parallel metal rails connected through R = 25.6 , 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.

Part A
Calculate the magnitude of the emf induced in the circuit.
Express your answer using two significant figures.
E =

Part B

Find the direction of the current induced in the circuit.

Find the direction of the current induced in the circuit.

Part C

Calculate the current through the resistor.
Express your answer using two significant figures.
