1. Consider the possibility of a new design for an electric train. The engine is driven by the force due to the vertical component of the Earth's magnetic field (10µT) on a conducting axle (L=3.0 m). Current is passed down one rail, through a conducting wheel, through the axle, through another conducting wheel, and then back to the source via the other rail. What current is needed to provide a modest 10-kN force? axle Current
