A zero resistance rod is sliding west along two zero resistance rails that are 2.3 m apart, on the ground where the earth’s magnetic field is nearly vertical with a magnitude of 0.60 mT. the bar is moving with a velocity 60 m/s. As it moves through the earth’s magnetic field an EMF is generated that creates a current flowing through the rails. a far away western resistance completes the circuit with a 5 Ω. What is voltage difference across the width of the rod, and which side will be at the higher potential, left or right facing the rod? b) What is the magnitude and direction of the force of magnetism acting on this rod?
