Linear motors in maglev train
CHAPTER 1
INTRODUCTION
1.1 INTRODUCTION
Transport along with communication, forms the core of day to day life of modern world. Conventional rail transport through wide spread is now being considered inefficient in terms of fuel consumption and is time consuming. A genuine replacement for railways which is not only fuel efficient but also highly comfortable and can attain unimaginable velocities of around 450 – 500kms/hr are Maglev Trains whose idea was given by Robert Goddard, an American Rocket scientist, in 1904 who gave a theory that trains could be lifted off the tracks by the use of electromagnetic rails. Many assumptions and ideas were brought about throughout the following years, but it was not until the 1970’s that Japan and Germany showed interest in it and began researching and designing.
The motion of the Maglev train is based purely on magnetism and magnetic fields. This magnetic field is produced by using high-powered electromagnets. By using magnetic fields, the Maglev train can be levitated above its track, or guide way, and propelled forward. Wheels and moving parts are eliminated on the Maglev train, allowing the Maglev train to essentially move on air without friction.

1.2 OUTLINE OF THE TOPIC
As the world continues to grow and as cities continues to become more crowded and congested, our normal modes of transportation will not be able to handle these overpopulated areas. The answer to this transportation problem lies in the world of electro magnetism and superconducting magnets. Electromagnets and superconducting magnets have allowed us to create a magnetic levitation train nicknamed “MAGLEV” that floats on the track instead of being directly on it. This has a lot of potential to create trains that are fast with low maintenance requirements.
Magnetism in elementary science simply states that like poles repel and opposites attract. When two magnets of which the same poles are towards each
