Maglev trains use electromagnetic levitation to lift and propel trains along guideways at high speeds with little friction. Magnets underneath the train lift it a few centimeters above the track, while side magnets keep it centered. This allows maglev trains to reach speeds over 400 mph. Projects exist in Germany, India, and the United States, with the goal of providing fast, efficient transport while reducing environmental impact compared to other modes of transportation.

Maglev Trains- Train That Fly on the AirOnkar Pawar
Maglev is short for Magnetic Levitation in which trains float on a guide way using the principle of magnetic repulsion. Each magnet has two poles. Now if you play with two magnets, you'll realize that opposite poles attract, whereas similar poles repel. This repulsive property of magnets is used in Maglev trains. However, instead of using permanent magnets, the principle of electromagnetism is used to create strong and large temporary magnets. When an electric current is passed through a coil of wire, magnetic field is generated around the coil according to Faraday's laws.
it is all about the working and little bit of history of the magnetic trains,
its a collection of knowledge,
find the references at end for more information
Maglev (derived from magnetic levitation) is a transport method that uses magnetic levitation to move vehicles without touching the ground. With maglev, a vehicle travels along a guideway using magnets to create both lift and propulsion, thereby reducing friction and allowing higher speeds.Maglev trains move more smoothly and more quietly than
wheeled mass transit systems. They are relatively unaffected by
weather. The power needed for levitation is typically not a large percentage of its overall energy consumption;most goes to overcome air resistance (drag), as with other highspeed transport. Maglev trains hold the speed record for rail transportation

Conclusion
It includes all about how MAGLEV trains works
based on principle of MAGLEV technology,advantages and drawbacks
am sure that u will definitely understood the topic.
3. Support System
•The electromagnets on the
underside of the train pull
it up to the ferromagnetic
stators on the track and
levitate the train.
•The magnets on the side
keep the train from moving
from side to side.
.This means there is no friction
between the train and the track!
4. - The basic principles involve the use of magnetism to levitate an
object.
-Maglev technology uses the principles of linear induction and
magnetism to propel the train forwards or backwards. Now imagine
the train is levitated by magnetism upwards as well as forwards.
-The combination of repulsive and attractive magnetic forces cause
the train to move towards a region of track. In the same fashion, to
slow down the train while it is moving, we must apply the repulsive
and attractive forces in such a way opposite to which the motion
started.
5. Batteries on the train power the system, and
therefore it still functions without propulsion.
The batteries can levitate the train for 30 minutes
without any additional energy.
Linear generators in the magnets on board the train
use the motion of the train to recharge the
batteries.
Levitation system uses less power than the trains air
conditioning.
6. Propulsion System
•The system consists of
aluminum three-phase cable
windings in the stator packs
that are on the guideway
•When a current is supplied
to the windings, it creates a
traveling alternating current
that propels the train
forward by pushing and
pulling.

8. •An alternating current is ran through electromagnet coils on the
guide walls of the guide way. This creates a magnetic field that
attracts and repels the superconducting magnets on the train and
propels the train forward.
•Braking is accomplished by sending an alternating current in the
reverse direction so that it is slowed by attractive and repulsive
forces.
9. •When the alternating current is reversed, the train brakes.
•Different speeds are achieved by varying the intensity of the
current.
•Only the section of track where the train is traveling is
electrified.
.
10. Application Information
Safety
•The trains are virtually impossible to derail because the train is
wrapped around the track.
•Collisions between trains are unlikely because computers are
controlling the trains movements.
Maintenance
• There is very little maintenance because there is no contact
between the parts.
11. Comfort
•The ride is smooth while not
accelerating..
Economic Efficiency
•The initial investment is similar to
other high speed rail roads. (Maglift is
$20-$40 million per mile and I-279 in
Pittsburg cost $37 million per mile 17
years ago.)
•Operating expenses are half of that of
other railroads.
•A train is composed of sections that
each contain 100 seats, and a train can
have between 2 and 10 sections.
12. •The linear generators produce electricity for the cabin of the
train.
Speed
•The train can travel at about 400 mph. (Acela can only go 150
mph)
•For trips of distances up to 500 miles its total travel time is
equal to a planes (including check in time and travel to airport.)
•It can accelerate to 200 mph in 3 miles, so it is ideal for short
jumps. (ICE needs 20 miles to reach 200 mph.)
13. •Noise Pollution
•The train makes little noise because it does not touch the track
and it has no motor. Therefore, all noise comes from moving air.
This sound is equivalent to the noise produced by city traffic.
14. Environment
•It uses less energy than existing transportation systems. For
every seat on a 300 km trip with 3 stops, the gasoline used per
100 miles varies with the speed. At 200 km/h it is 1 liter, at 300
km/h it is 1.5 liters and at 400 km/h it is 2 liters. This is 1/3 the
energy used by cars and 1/5 the energy used by jets per mile.
•The tracks have less impact on the environment because the
elevated models (50ft in the air) allows all animals to pass, low
models ( 5-10 ft) allow small animals to pass, they use less land
than conventional trains, and they can follow the landscape better
than regular trains since it can climb 10% gradients (while other
trains can only climb 4 gradients) and can handle tighter turns.
16. India
Pune (Pimple Saudagar) –
Mumbai (Panvel): The
Indian Ministry is currently
in the process of reviewing
a proposal to start a
Maglev train system in
India. It has already been
estimated that the cost to
complete this process
would be over $30 Billion.
17. .U.S.A -The united states Congress is planning to spend
$1 billion for a test project that either connect Pittsburgh’s suburbs
its airport or Baltimore to the Washington international airport .
. GERMANY - A Transrapid connection linking the
city centre of the Bavarian capital Munich to the airport (37 km) had
been planned. It promised to reduce the connection time from
about 40 minutes by the existing S-Bahn (German city railway
system) to 10 minutes.
18. . Maglev trains use magnets to levitate and
propel the trains forward.
. Since there is no friction these trains can
reach high speeds.
. It is a safe and efficient way to travel.
19. . Only the part of the track that is used will be electrified
so no energy is wasted.
. Linear generators will produce all the electricity needed
in the train’s interior.
.The train is earthquake proof because the greater space
(10 cm) between the track and the train leaves more room
for track deformation
