Maglev (derived from magnetic levitation) is a transport method that uses magnetic levitation to move vehicles without touching the ground. With maglev, a vehicle travels along a guideway using magnets to create both lift and propulsion, thereby reducing friction by a great extent and allowing very high speeds.
- Currently the world’s fastest maglev train, the Shanghai Transrapid, whisks passenger to and from the Shanghai airport at 501 km/h (311 mph).
- Mag-Lev Train Could Reach 2900 Km/h – Jiaotong’s prototype runs inside a vacuumed loop, or evacuation tube (ETT). Inside the Jiaotong ETT air resistance is effectively reduced to zero – maximizing the maglev’s potential.

Acela trains, which hit 150 mph – fastest trains in the U.S. for now
- New 300 MPH Floating Train – Japan is track testing its new high-speed magnetic levitation (maglev) train, which is designed to travel at 310 mph. The L0 maglev train floats above its track and is propelled by powerful magnets, eliminating friction that limits the speeds of conventional trains.
- 11 Incredibly Fast Trains – Among the fastest in the world, these trains regularly top 200 mph and even crack above the 300 mph mark.
Superconducting magnets are some of the most powerful electromagnets known. They are used in MRI/NMR machines, mass spectrometers, and the beam-steering magnets used in particle accelerators. They can also be used for magnetic separation, where weakly magnetic particles are extracted from a background of less or non-magnetic particles, as in the pigment industries.
