INTRODUCTION
MAGNETIC LEVITATION
Magnetic levitation, maglev, or magnetic suspension is a method by
which an object is suspended above another object with no support other than
magnetic field .The electromagnetic force is used to counteract the effects of thegravitational force.
A substance which is diamagnetic repels a magnetic field. All materials have
diamagnetic properties, but the effect is very weak, and usually overcome by the
object's paramagnetic or ferromagnetic properties, which act in the opposite
manner. Any material in which the diamagnetic component is strongest will be
repelled by a magnet, though this force is not usually very large. Diamagnetic
levitation can be used to levitate very light pieces of pyrolytic graphite or
bismuth above a moderately strong permanent magnet. As water is
predominantly diamagnetic, this technique has been used to levitate water
droplets.
Magnetically Levitated Trains (MAGLEV)
The principal of a Magnet train is that floats on a magnetic field and is propelled
by a linear induction motor. They follow guidance tracks with magnets. These
trains are often referred to as Magnetically Levitateda train which is abbreviated
to Maglev. Although maglev don't use steel wheel on steel rail usually associated
with trains, the dictionary definition of a train is a long line of vehicles traveling
in the same direction - it is a train.

3/3
A super high-speed transport system with a non-adhesive drive system that
is independent of wheel-and-rail frictional forces has been a long-standing dream
of railway engineers. Maglev, a combination of superconducting magnets
and linear motor technology, realizes super high-speed running, safety,
reliability, low environmental impact and minimum maintenance
TECHNOLOGY AND WORKING OF MAGLEV TRAINS
Basically the construction of the maglev train depends on 3 different working
forces. They are,
LEVITATION FORCE PROPULSION FORCE LATERAL GUIDING FORCE
MAGLEV METHODS
Repulsion between like poles of permanent magnets or electromagnets. Repulsion between a magnet and a metallic conductor induced by relative
motion.
Repulsion between a metallic conductor and an AC electromagnet. Repulsion between a magnetic field and a diamagnetic substance. Repulsion between a magnet and a superconductor. Attraction between unlike poles of permanent magnets or electromagnets. Attraction between the open core of an electromagnetic solenoid and a
piece of iron or a magnet.
Attraction between a permanent magnet or electromagnet and a piece ofiron.
Attraction between an electromagnet and a piece of iron or a magnet, withsensors and active control of the current to the electromagnet used to
maintain some distance between them.
Repulsion between an electromagnet and a magnet, with sensors and activecontrol of the current to the electromagnet used to maintain some distance
between them.
