A 10cm long wire is pulled along a U-shaped conducting rail in a perpendicular magnetic field. The total resistance of the wire and rail is 0.35 Ω. Pulling the wire with a force of 1.0 N causes 4.0 W of power to be dissipated in the circuit. a. What is the speed of the wire when pulled with a force of 1.0 N?
b. What is the strength of the magnetic field?
