EMS systems use superconducting magnets to create a magnetic field that levitates the vehicle. The superconducting magnets are cooled to very low temperatures, which allows them to conduct electricity with no resistance. This creates a very strong magnetic field. The vehicle is levitated by the magnetic field, which pushes against the magnets on the underside of the vehicle.
EDS systems use repulsive forces between magnets to levitate the vehicle. The magnets on the vehicle and the magnets on the track are both energized with the same polarity. This creates a repulsive force between the magnets, which levitates the vehicle.
Maglev vehicles are able to levitate without touching the track, which reduces friction and allows them to travel at very high speeds. Some maglev systems can reach speeds of over 300 miles per hour.
