MAGNETIC LEVITATION
Abstract:
The use of natural resources in our day to day life is increasing which leads to shortage of these resources in the upcoming generation,mainly in transportation we are wasting a lot of crude oils and other resources which leads to global earthing. So in this paper we’re discussing about magnetic levitation and the uses in transportation .
Magnetic levitation is being used in ultrahigh speed trains(upto 300km/h) which float in
the air about 100mm to 300mm above the metallic track.they do not have any wheels and do not require the traditional steel rail.A powerful electromagnet (whose coils are cooled to about 4degree K by liquid helium) fixed underneath the train moves across the conduc- ting rail,thereby inducing current in the rail. This gives rise to vertical force (called force of levitation) which keeps the train pushed up in the air above the track linear motors are used to propel the train.
A similar magnetic levitation system of transit is being considered for connecting vivek -vihar in east Delhi to vikaspuri in west Delhi. The system popularly known as magneto-bahn (M-Bahn) completely eliminates the centuries-old ‘steel-wheel-over steel rail’ tra- ction. The M-Bahn train floats in the air through the principle of magnetic levitation and propulsion is by linear induction motors. There is 50% decrease in the train weight and 60% reduction in energy consumption for propulsion purposes. The system is extraordin- arily safe (even during an earthquake) and the operation is fully automatic and computer- ised
