Maglev trains are trains which are suspended, guided and propelled (moved forward) by magnetic forces. The track of the maglev train is called the guide-way. Working of the maglev trains can be studied under the following. 1  Levitation. 2  Propulsion. 3  Guidance.
Superconductors. Maglev trains are held just above the tracks by powerful superconducting electromagnets. At low temperatures, some metals can become superconductors. They will have little or no electrical resistance. For example, mercury is a liquid metal.It solidifies at â38.8 Â°C and becomes a superconductor at â268.8 Â°C.hey will have little or no electrical resistance. For example, mercury is a liquid metal.
