Parallel conducting tracks, separated by 2.79 cm, run north and south. There is a uniform magnetic field of 1.27 T pointing upward (out of the page). A 0.0354-kg cylindrical metal rod is placed across the tracks and a battery is connected between the tracks, with its positive terminal connected to the east track. If the current through the rod is 3.30 A, find the magnitude of the magnetic force on the rod. What is the direction of the magnetic force on the rod?
