Levitation. Maglev trains have no contacts with the rails while they move forward. They are levitated on the guide-way with the help of magnetic forces. Levitation is the process by which an object is suspended against gravity in a stable position without any physical contact.
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.
