Maglev Train is a Magnetic
Levitated
( no friction )
train.
If you ever played with
magnets , you know that unlike poles attract each other and like poles repel
each other.
This is the basic
principle behind Maglev Trains.
In Maglev Trains there are
strong electromagnets attached at the bottom of the train ( i.e ;- at the place
of wheels ) and also at the place of railway tracks.
These electromagnets
produces a repulsive action and hence makes the train at some distance above
from the tracks.
The big difference between
Maglev train and conventional trains is that Maglev trains do not have an
engine and wheels.
But it has a source which
produces thrust energy for its forward movement ( e.g ;- big fan ).
Because of the elimination
of wheels and rail tracks and also because the train is at some distance above
from the tracks , there is no mechanical friction and hence energy losses are
minimized.
At present Maglev Trains
are the fastest trains in the world with a top speed of 430 km/h.
