<HW 30 Problem 30.3 - Enhanced - with Hints and Feed 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 0.350 2. Pulling the wire at a steady speed of v = 4.00 m/s causes 3.50 W of power to be dissipated in the circuit. %3D
