Maglev trains use magnetic levitation to float and guide the train along a guideway without touching the ground. This eliminates friction and allows the trains to reach speeds over 300 mph. Maglev trains are propelled through either electromagnetic or electrodynamic suspension and guided electromagnetically. While maglev trains provide benefits like high speed, low noise and maintenance compared to wheeled trains, they require much higher initial costs that have prevented widespread adoption. Research continues in many countries to develop practical maglev train systems.

2. ABSTRACT
•By employing no wheels, maglev eliminates the
friction, and concomitant heat, associated with
conventional wheel-on-rail train configurations.
•“Driving without wheels, Flying without wings”
deals with the present scenario of magnetic
levitation (maglev) with Linear induction motor
(LIM)

• 1900 – Robert and Emile Bachelet
• 1970 – German and Japanese engineers start
research and development towards their
versions of Maglev technology.

14. • Less energy consumption because no rail-
track friction
• Requires no fossil fuel which can harm the
environment.
• Less noise pollution since the train never hits
the track
• MagLev guideways and trains take up less
space than conventional trains

15. AdvantagesAdvantages
• Because the train floats along there is noBecause the train floats along there is no
contact with the ground and therefore nocontact with the ground and therefore no
need for any moving parts.Hence there are noneed for any moving parts.Hence there are no
components that would wear out.components that would wear out.

17. ApplicationsApplications
NASA plans to use magnetic levitation
for launching of space vehicles into low
earth orbit.
The mining industry will also benefit
from Maglev.

19. CONCLUSION
 Research on this ‘dream train’
has been going on for the last
30 odd years in various parts
of the world.
