Mag-Lev trains can reach high speeds in part by minimizing the friction associated with moving over the ground. The strong magnetic fields necessary to lift a train are generated by superconducting electromagnetic coils. An engineer believes that each of the solenoids used in the train track needs to generate a field no less than 4.0 Teslas using a current of 6.5*102A. If the coil can be no longer than 25 cm in length, how many windings would it need?
