I am looking for Information On Magnetic levitation. If there is
anyone out There who can give any information at all on this subject. Index Key:
Magnetic levitation is simple in principle - there are two ways
to do it: place two north poles close together and they repel,
so if the higher one is constrained to always be the same orientation
relative to the lower one (for example by have a circular magnet
with a hole in the middle and a rod through the hole keeping it
in place) then the higher one can stay levitated. The second
way is using superconductors, which repel small enough magnetic
fields (but superconductors work only at low temperatures).
Magnetic levitation has been used for a number of high-speed
train systems currently under development. Oh - there is a third
way to do it - by using attraction rather than repulsion, but
that requires a more careful balancing of forces.
Try looking in your local library for recent business articles
on magnetic levitation, particularly these trains.
