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.
Maglev or Magnetic Levitation trains are not a new idea. The first Maglev train was invented in 1902 requiring many years for its eventual development. The idea during the earlier days of the 20th century was that a train would levitate just about the track through the use of powerful magnets to keep it afloat. Considered a futuristic idea for its time, the invention of the train by Alfred Zehden was awarded its first patent in 1905. Many scientists around the globe were working on the same idea but it was Zehdenâs that is credited with the invention of the Maglev.
