A 8.00-cm-long wire is pulled along a U-shaped conducting rail in a perpendicular magnetic field. The total resistance of the wire and rail is 0.300 Ω. Pulling the wire at a steady speed of v = 4.00 m/s causes 4.50 W of power to be dissipated in the circuit. How big is the pulling force? What is the strength of the magnetic field?
