MAGNETIC LEVITATION

MAGNETIC LEVITATION

ABSTRACT:

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.

INTRODUCTION:

The word levitation is derived from a latin word “LEVIS”,which means light. Magnetic levitation is the use of magnetic fields to levitate a metallic object. By manipulating magnetic fields and controlling their forces an object can be levitated. When the like poles of two permanent magnets come near each other, they produce a mutually repulsing force that grows stronger as the distance between the poles diminishes. When the unlike poles of two permanent magnets are brought close to each other, they produce a mutually attractive force that grows stronger as the distance between them diminish A levitation system designed around the attractive force between unlike poles would require a perfect balance between the attractive magnetic force and the suspended weight In the absence of a perfect lift and weight force profile, the conveyance would either be pulled up toward the magnets or would fall. This simple illustration of magnetic levitation shows that the force of gravity can be counterbalanced by magnetic force.
