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 earths magnetic field on a conducting axle Current is passed down one coil into a conducting wheel through the axle through another conducting wheel then back to the source via the other rail i What current is needed to provide a modest 10 KN force Take the vertical component of theearth s field be 10 T the length of axle to be 3 0 m ii How much power would be lost for each of resistivity in the rails iii Is such a train unrealistic
