This makes getting to space less expensive. Most of the weight is iron used in the motor. The track is shrouded with nonmagnetic stainless steel. Now, with larger-scale experiments, we want to demonstrate that control can be maintained at high speeds along the maglev track. Through demonstrations on Marshall Center's track, NASA seeks to learn more about aerodynamics, magnetic fields, and energy storage devices associated with maglev.
Different poles attract each other while similar pole repel each other.
By using the similar pole repulsion the vehicle is levitated. Magnetic Levitation Trains High-speed magnetic levitation trains, called maglevs, have the advantages of being faster, smoother, and quieter than conventional trains. Several countries, including Japan, Germany, and the United States have maglev train development programs. Electricity and Magnetism Motors and generators work because of the principle of electromagnetic induction, discovered by British scientist Michael Faraday in 1831. This is how a generator works.
