Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. The electromagnetic force is used to counteract the effects of the gravitational force.
Please submit sites directly related to the transportation aspect of maglev, including projects, companies, technologies, and resources.
