 Advantages and disadvantages
 Conclusion

3.  Magnetic levitation is a method by which an object is
suspended with no support other than magnetic fields.
 Magnetic pressure is used to counter act the effects of
gravitational forces.
 The magnetic pressure of a magnetic field can be calculated
by : Pmag=B2/2μ0 .

4.  Diamagnetic materials are the substances which repels the
magnetic lines of force in a magnetic field.
 Superconductors may be considered perfect diamagnets.
(μr = 0).
 A magnet levitating above a high temperature,
super conductor, cooled with liquid nitrogen.
 Persistent electric current flows on the surface
of the superconductor, acting to exclude the
magnetic field of the magnet .

5.  A new transportation mode has occurred that can clearly
compete with planes in both speed and safety. They are
called MAGLEV TRAINS.
 Magnetic levitation principle can also be used in wind
turbines and we can call it as MAGLEV WIND TURBINES

6.  This is a vehicle that can be
suspended and propelled on
a guidance track made with
magnets.
 The MAGLEV trains are
known to have more speed,
smoothness and less sound.
 The trains are also
aerodynamically designed
which enables them to
reach great speeds like
300 miles/hour

7.  The train will be floating
about 10mm above the
magnetic guiding track.
 In MAGLEV trains, the power
to propel the train is
provided by the magnetic
fields created by the electric
coils kept in the guidance
tracks.

8.  There are two kinds of
wind turbine, which are
HAWT ,VAWT .
 Guangzhou Energy
Research Institute
under China’s
Academy of Science
introduced magnetic
levitation principle in
wind turbine.

9.  Maintenance.
 Reduction in noise.
 High speed
 They are more expensive.

10.  Magnetic levitation is the phenomenon of rising up a material
with the help of superconductors and the other magnetic
materials.
 The one of the remarkable application of the magnetic
levitation is maglev train which travels with a velocity of 160
m/s.
 The magnetic levitated wind turbine has high efficiency and
can produce large amount of wind power.
 The magnetic control system is one of the rising phenomenon
in modern technology which is application of magnetic
levitation.
