A 9.0 cm long wire is pulled along a U-shaped conductor rail in a perpendicular magnetic field. Is the total resistance of wire and rail 0.34? . Pulling the wire with a force of 1.1 N results in the dissipation of 4.4 W of power in the circuit. What is the speed of the wire when pulled with 1.1N? What is the strength of the magnetic field? Thanks!
