This document discusses different ways to achieve magnetic levitation, including mechanically constrained levitation using two magnets, diamagnetic levitation using materials that repel magnetic fields, and superconductors which expel magnetic fields due to the Meissner effect. It also outlines applications of magnetic levitation such as maglev trains which use electromagnetic or electrodynamic suspension, magnetic bearings for industrial machinery, levitation melting using induction heating, and maglev elevators employing electrodynamic suspension.
4. 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.
5. 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.
6. 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.
