Magnetic Parameters
R
A rail system is formed in a magnetic
field directed out of the page as diagrammed above. The rod remains in contact with the rails with zero friction as it moves to the right at a constant velocity of v15ms due to an external force. The distance from one rail to the other is 0.087m. The rails and the rod have no resistance, but the resistor has a resistance of 0.0055 Ohms. The magnetic field has a magnitude of 0.035T. What is the magnitude and direction of the extemal force required to keep the rod moving at a constant velocity?
