Strength of the Magnetic Field
Not what you're looking for?
A 10 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 0.20 ohms. Pulling the wire with a force of 1.oN causes 4.0 W of power to be dissipated in the circuit. A) What is the speed of the wire when pulled with 1.0N? B) What is the strength of the magnetic field?
