Magnetic levitation
Define :
Magnetic levitation is a method by which an object is suspended with no support
other than the magnetic fields. Magnetic pressure is used to counteract the effects
of the gravitational and any other accelerations.
Magnetic levitation is also known as Maglev (or) Magnetic suspensions.
DIFFERENT WAYS TO MAGNETICALLYLEVITATE AN OBJECT
• Mechanically constraint
• Diamagnetic levitation
• Superconductors
MECHANICALLY CONSTRAINT
Two magnets are mechanically constrained along a single vertical axis, this will act to levitate one of the magnets above the other.
Also known as Pseudo levitation
DIAMAGNETIC LEVITATION
Diamagnetic materials repel a magnetic field.Less than ZERO magnetic permeability.By surrounding a diamagnetic material with a magnetic field, it can be held in a stationary position.
SUPERCONDUCTORS
Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields.Superconductors works on the principle of MEISSNER EFFFECT
APPLICATION
MAGNETIC LEVITATION
Maglev, or magnetic levitation, is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnet.
• Maglev
• Magnetic bearings
APPLICATION
Industrial equipment such as pumps, generators, motors use levitation to support moving machinery without physical contact.
