Magnetic Levitation Train (Maglev)

Abstract

The term ‘Levitation’ refers to a class of technologies that uses magnetic levitation to propel Vehicles with magnets rather than with wheels, axles and bearings. Maglev derived from magnetic levitation uses magnetic levitation to propel vehicles, it is a concept which basically uses the like poles of the magnets to propel an object in the air, in this case the vehicle is levitated a short distance away from a guide way using magnets to create both lift and thrust maintaining a constant gap while traveling at high speed. Maglev has became the fastest growing technology in the field of railways infrastructure, these frictionless trains who have no contact with any kind of surface are the future. Maglev trains which are based on the principle of maglev have been compared with high speed transportation such as air transport. High-speed maglev trains promise dramatic improvements for human travel widespread adoption occurs. Maglev trains move more smoothly and somewhat more quietly as there is no contact with ground and need no moving parts reducing maintenance cost as compared to subway trains. Apart from all this, there is no possibility of any parts wearing out, there is less noise because no steel wheels running on steel tracks and being operated totally on electrical energy these trains are pollution free.it is desirable to not only levitate the train but also at desired position and continuously track at desired path.
