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.

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.
