Abstract :
Magnetic
levitation means “to rise and float in air”. The Maglev system is made possible
by the use of electromagnets and magnetic fields.
The basic principle behind
Maglev is that if you put two magnets together in a certain way there will be a
strong magnetic attraction and the two magnets will clamp together. This is
called "attraction". If one of those magnets is flipped over then
there will be a strong magnetic repulsion and the magnets will push each other
apart. This is called "repulsion". Now imagine a long line of magnets
alternatively placed along a track. A line of alternatively placed magnets on
the bottom of the train.
If these magnets are properly controlled the trains
will lift of the ground by the magnetic repulsion or magnetic attraction. On
the basis of this principle, Magnetic Levitation is broken into three main
types of suspension or levitation; they are (a) Electromagnetic Suspension.
(b) Electrodynamic
Suspension.
(c) Inductrack
Maglev
trains float on a cushion of air: they do not sit on a track. The reason it can
do this is because there are extremely powerful magnets on the track, and there
are extremely powerful magnets on the bottom of the train. It was created like
this because the lack of friction the train has now can cause it to reach
speeds of up to 310 miles per hour. Also the maglev train has a very
aero-dynamic design so therefore it can move faster.
The maglev trains do not
have wheels because they float. This keeps the train from having bumps, or
rocking. The magnets on the track and the train are facing so that the same
pole is towards the other. This will cause the magnets to strongly repel so
that will cause the train to float.
There is a extremely powerful electromagnet
at the end of the track that can cause the magnets on the train to go forward
or backward. This would not work if the train was not floating. Maglev trains
do not have engines. The magnets on the track create a large magnetic field that
causes the train to move. This causes the maglev system to be very
eco-friendly, saving tons of fossil fuels. The U.S. is trying to make one of
these trains so we can save fuel. The reason we are having trouble doing that
is they cost so much money we can’t afford them in these economic times.
