Introduction
Magnetic Levitation is a way to suspend objects in air without any support, as if in defiance of gravity. An nameless phenomenon of the past which is now being put to use in a variety of interesting and useful applications. As a child we must have seen a ping pong ball being levitated on an air stream at the output pipe of a vacuum cleaner. Magnetic levitation, as well known as maglev is used in a similar way to levitate objects in air without any support, using magnetic field. Levitation is the process by which an object is suspend against gravity, in a stable position, without physical contact. For levitation on Earth, first, a force is required directed vertically upwards and match to the gravitational force, second, for any puny displacement of the levitating object, a go(a) force should appear to stabilize it. The stable levitation can be naturally achieved by, for example, magnetic or aerodynamic forces. Though any electromagnetic force could be used to counteract gravity, magnetic levitation is the most common. Though any electromagnetic force could be used to counteract gravity, magnetic levitation is the most common. Diamagnetic materials are commonly used for demonstration purposes.
In this case the returning force appears from the interaction with the screening currents. For example, a superconducting sample, which can be considered either as a perfect diamagnet or an ideally hard superconductor, easily levitates an ambient external magnetic field. In very strongmagnetic field, by means of diamagnetic levitation even small live animals have been levitated.
2 The word levitation is derived from a Latin word LEVIS, which means light. Magnetic levitation is the use of magnetic palm to levitate a metallic object. By manipulating magnetic field and controlling their forces an object can be levitated. When the like poles of ii permanent magnets come near each other, they produce a mutually repulsing force that grows...If you want to get a spacious essay, order it on our website: Orderessay
