Maglev trains use magnetic levitation to float above a guideway without touching it. The first commercial maglev in 1984 connected Birmingham Airport to a train station in England, but it closed in 1995 due to reliability issues. British engineer Eric Laithwaite developed the first working linear induction motor in the 1940s, enabling advanced transit systems without physical contact between vehicles and guideways. Maglev trains use electromagnetic and electrodynamic suspension for levitation and propulsion via magnets and electromagnetic coils. While offering benefits like high speeds and low maintenance, maglev systems require expensive infrastructure and are currently only implemented in a few countries.
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

Seminar on Magnetic levitation and its applicatonRahul Shaw
Magnetic levitation is the use of magnetic fields to levitate a (usually) metallic object. Manipulating magnetic fields and controlling their forces can levitate an object.
In this process an object is suspended above another with no other support but magnetic fields.
The electromagnetic force is used to counteract the effects of gravitation. But it has also been proved that it is not possible to levitate using static, macroscopic, `classical' electromagnetic fields.
The forces acting on an object in any combination of gravitational, electrostatic, and magnetostatic fields will make the object's position unstable.
The reason a permanent magnet suspended above another magnet is unstable is because the levitated magnet will easily overturn and the force will become attractive. If the levitated magnet is rotated, the gyroscopic forces can prevent the magnet from overturning.
Several possibilities exist to make levitation viable.
It is possible to levitate superconductors and other diamagnetic materials, which magnetise in the opposite sense to a magnetic field in which they are placed.
A superconductor is perfectly diamagnetic which means it expels a magnetic field (Meissner-Ochsenfeld effect). Other diamagnetic materials are commonplace and can also be levitated in a magnetic field if it is strong enough.Diamagnetism is a very weak form of magnetism that is only exhibited in the presence of an external magnetic field.
The induced magnetic moment is very small and in a direction opposite to that of the applied field. When placed between the poles of a strong electromagnet, diamagnetic materials are attracted towards regions where the magnetic field is weak.
Diamagnetism can be used to levitate light pieces of pyrolytic graphite or bismuth above a moderately strong permanent magnet. As water is predominantly diamagnetic, this property has been used to levitate water droplets and even live animals, such as a grasshopper and a frog.
Superconductors are perfect diamagnets and when placed in an external magnetic field expel the field lines from their interiors (better than a diamagnet). The magnet is held at a fixed distance from the superconductor or vice versa. This is the principle in place behind EDS (electrodynamic suspension) maglev trains. The EDS system relies on superconducting magnets.
A maglev is a train, which is suspended in air above the track, and propelled forward using magnetism. Because of the lack of physical contact between the track and vehicle, the only friction is that between the carriages and air. So maglev trains can travel at very high speeds (650 km/h) with reasonable energy consumption and noise levels

2. IntroductionIntroduction
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.
3. HistoryHistory
The first commercial maglev people
mover was simply called "MAGLEV" and
officially opened in 1984 near
Birmingham, England. It operated on an
elevated 600 m (2,000 ft) section of
monorail track between Birmingham
Airport and Birmingham International
railway station, running at speeds up to
42 km/h (26 mph). The system was
closed in 1995 due to reliability problems.
4. DevelopementDevelopement
In the late 1940s, the British electrical engineer Eric
Laithwaite, a professor at Imperial College London,
developed the first full-size working model of
the linear induction motor. He became professor of
heavy electrical engineering at Imperial College in
1964, where he continued his successful development
of the linear motor.Since linear motors do not
require physical contact between the vehicle and
guideway, they became a common fixture on
advanced transportation systems in the 1960s and
70s. Laithwaite joined one such project, the tracked
hovercraft, although the project was cancelled in
1973.

-uses repulsive force between 2
6. Basic principle of MAGLEVBasic principle of MAGLEV
Maglev trains have to perform the
following functions to operate in High
speed
1. Levitation 2. Propulsion 3. Lateral
7. LevitationLevitation
Magnetic Levitation is method by which
an object is suspended with no support
other than magnetic fields.
The magnetic force is used to counteract
the effect of the gravitational
Acceleration and any other accelerations
8. Propulsion System
•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. Lateral GuidanceLateral Guidance
When one side of the train nears the side of
the guideway, the super conducting magnet on
the train induces a repulsive force from the
levitation coils on the side closer to the train
and an attractive force from the coils on the
farther side. This keeps the train in the center.
10. How MagLev WorksHow MagLev Works
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
A computer changes the amount
of current to keep the train 1cm
above the track.
This means there is no friction
between train and track

12. Levitation System’s PowerLevitation System’s Power
SupplySupply
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.
