Determine how much power would be lost

Reference no: EM13674435

Consider the possibility of a new design for an electric train. The engine is driven by the force on a conducting axle due to the vertical component of Earth's magnetic field. Current is down one rail, through a conducting wheel, through the axle, through another conducting wheel, and then back to the source via the other rail.

(a) Determine what current is needed to provide a modest 5 kN force? Take the vertical component of Earth's field to be 10 µT and the length of the axle to be 3.0 meter.

(b) Determine how much power would be lost for each ohm of resistance in the rails?
