MAGNETIC LEVITATION
DIFFERENT WAYS TO MAGNETICALLYLEVITATE AN OBJECT
• Mechanically constraint
• Diamagnetic levitation
• Superconductors
• Rotational stabilization
• Servo stabilization
MECHANICALLY CONSTRAINT
• Also known as pseudo Levitation.
• Two magnets are mechanically constrained along a single vertical axis, this will act to levitate one of the magnets above the other.
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 effect.

MAGNETIC LEVITATION
Maglev, or magnetic levitation, is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnet.ELECTROMAGNETIC SUSPENSION
ANDELECTRODYNAMIC SUSPENSION
APPLICATION
ELECTROMAGNETIC SUSPENSION
ELECTRODYNAMIC SUSPENSION
APPLICATION
•Magnetic bearings
Industrial equipment such as pumps, generators, motors use levitation to support moving machinery without physical contact.
APPLICATION
• Levitation melting
Levitation melting works on the principle of Induction heating.
INDUCTION HEATING
APPLICATION
•Maglev elevator
Maglev elevator works on the principle of EDS (Electrodynamic suspension).
