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, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic pressure is used to counteract the effects of the gravitational and any other accelerations.
Earnshaw's theorem proves that using only static ferromagnetism it is impossible to stably levitate against gravity, but servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents permit this to occur.
In some cases the lifting force is provided by magnetic levitation, but there is a mechanical support bearing little load that provides stability. This is termed pseudo-levitation.
Magnetic levitation is used for maglev trains, magnetic bearings and for product display purposes.
MAGNETIC LEVITATION ?It is use of magnetic fields to levitate a metallic object .By manipulating magnetic fields and controlling their forces an object can be levitated. Because of the growing need for quicker and more efficient methods for moving people and goods, researchers have turned to a new technique, one using electromagnetic rails and trains. This rail system is referred to as magnetic levitation, or maglev. Maglev is a generic term for any transportation system in which vehicles are suspended and guided by magnetic forces. Instead of engines, maglev vehicles use electromagnetism to levitate (raise) and propel the vehicle. Alternating current creates a magnetic field that pushes and pulls the vehicle which weighs almost about 1500 tonnes and keeps it above the support structure, called a guide way. Another major application of magnetic levitation is ELEKTROMAG. "ELEKTROMAG"-- Magnetic Sheet Floaters have been designed for easy handling of stacked sheets in production jobs.
