HOW WORKS?When a magnet approaches a superconductor that has
previously been cooled below its transition temperature until get a
zero resistance into materia. When this happens an electric current
creates an opposite magnetic field of the magnetSo as not to
superconductor gives electrical resistance, the induced current
flows and creates a repulsive force that counteracts the weight of
the magnet and holds it in the air.
Applications and AdvantagesThis technology has been employed in
various elements such as cellular system having a sliding panel,
however, where it stands is in the construction of high-speed
trains, which slide on the superconductors and involves a high
performance by requiring only a initial circular drive with
frictionless surfaceDynamic effects based applications require a
large amount of energy. The properties of attraction and repulsion
between magnets and superconductors has improved a lot to be
considered very stable systems and energy consumption is reduced
drastically.
HOW TO MAKE ONE?A superconductor material A wooden boardLiquid
nitrogenLiquid nitrogenStyrofoamA magnet
First we need to put the superconductor into base of styrofoam
with liquid nitrogen, the temperature going to get down to certain
critical temperature. When Superconductor reaches this temperature.
The magnetic fields are expelled for the superconductor after that
we need to make two big circles on the wooden board for put the
superconductor with liquid nitrogen into styrofoam.We need to paste
very well and we need to a magnet very large or some parts placed
with a rail like a path of trains when we put in place the wooden
board is suspended in the air like magic
