Magnetic levitation, or maglev, is a method of supporting and propelling objects using magnets. Using the repellent force of superconductive magnets, vehicles, such as trains, may be suspended above a track or guideway. Continuously changing the polarity in alternate magnets causes a series of magnetic attractions and repulsions, which moves the vehicle along the track quickly and quietly. What is the highest recorded speed of a maglev train? Discuss
