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...
