MAGLEV - Magnetic Levitation

• Magnetic levitation is the use of magnetic fields to levitate a metallic object.

• Manipulating magnetic fields and controlling their forces can levitate an object.

• Using either Ferromagnetism or Diamagnetism object can be levitated.

• A superconductor is perfectly diamagnetic and electromagnets can exhibit varying levels of ferromagnetism

Introduction

Why maglev trains needed ?

Increasing pollution level from automobiles

Depleting fuel resources Limited range of buses and cars Need for fast

Basic Principle of Maglev Trains

Maglev trains have to perform the following functions to operate in high speeds

1.Leviation

2.Propulsion

3.Lateral Guidance

LEVITATION

BALANCE

UPLIFT

LEVITATIONS TECHNIQUES

1. Electromagnetic Suspension2. Electrodynamic Suspension

•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.

1)The Maglev's speed can vary from standstill to full operating speed by simply adjusting the frequency of the alternating current.

2) To bring the train to a full stop, the direction of the travelling field is reversed.

• They do not have an engine.• They do not use FOSSIL FUEL.• Fast• Quiet• Easy maintenance• Environmentally friendly– No emissions

ADVANTAGES …

• Safety issues–Or synchronization could cause serious accidents

• Expensive to build– $10-30 million per mile(1.6 km)

DISADVANTAGES …

CONCLUSION

They consume less energy.

Require no engine.

Move faster than normal trains because they are not affected by ground friction.

 Incompatible with existing rail lines, unlike traditional high-speed rail.

Initial cost is very high.
