An L = 49.0 cm wire is moving to the right at a speed of v = 7.70 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 = 0.850 T and is directed into the screen. What is the emf & induced in the wire? E = 3.3 Incorrect The induced emf causes a current to flow in the circuit formed by the moving wire and the rails. In which direction does the current flow around the circuit? F = counterclockwise O clockwise If the moving wire and the rails have a combined total resistance of 1.55 92, 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. V 0.799 Incorrect N Ø 10 Ø
