An L = 47.0 cm wire is moving to the right at a speed of v = 7.90 m/s across two parallel wire rails that are connected on the left side, as shown in the figure. The whole apparatus is immersed in a uniform magnetic field that has a magnitude of B = 0.890 T and is directed into the screen. What is the emf & induced in the wire? The induced emf causes a current to flow in the circuit formed by the moving wire and the rails. If the moving wire and the rails have a combined total resistance of 1.75 2, what applied force F would be required to keep the wire moving at the given velocity? Assume that there is no friction between the moving wire and the rails.
