Magnetic Levitation
 Magnetic levitation is the use of magnetic fields to levitate a (usually)
metallic object.
 Manipulating magnetic fields and controlling their forces can levitate an
object.
 Using either Ferromagnetism or Diamagnetism object can be levitate
 Most important application of Magnetic Levitation is magnetic lift trains.

5. “Maglev Train”
 1750-John Mitchell where he noticed the repulsion of two
magnets when the same pole of each was put together.
 1900-Robert Goddard and Emile Bachelet conceived the concept
of frictionless trains.
 1990-U.S Federal Government supports & implements the
National Maglev Imitative(NMI).
HISTORY OF MAGLEV

6. “Maglev Train”
Electromagnetic Suspension(EMS)
Electromagnetic Suspension uses electromagnets to
levitate the train

7. “Maglev Train”
Electrodynamic Suspension
Electrodynamics Suspension uses
Superconductors for levitation, propulsion and
lateral guidance

Basic Principle of Maglev Trains
• Maglev trains have to perform the
following functions to operate in high
speeds
1.Levitation
2.Propulsion
3.Lateral Guidance

9. “Maglev Train”“Maglev Train”
• An EDS system can provide both levitation and
propulsion using an onboard linear motor.
• EMS systems can only levitate the train using the
magnets onboard, not propel it forward.

10. “Maglev Train”
• The passing of the superconducting magnets by levitation coils
on the side of the track induces a current in the coils and creates
a magnetic field. This pushes the train upward so that it can
levitate 10 cm above the track.
PRINCIPLE OF MAGNET LEVITATION

11. “Maglev Train”
o The propulsion coils located on the sidewalls on both sides of the guide way
are energized by a three-phase alternating current from a substation, creating
a shifting magnetic field on the guide way.
o The on-board superconducting magnets are attracted and pushed by the
shifting field, propelling the Maglev vehicle.
o Braking is accomplished by sending an alternating current in the reverse
direction so that it is slowed by attractive and repulsive forces.
PRINCIPLE OF PROPULSION

12. “Maglev Train”
•When one side of the train nears the side of the guideway, the
super conducting magnet on the train induces a repulsive force
from the levitation coils on the side closer to the train and an
attractive force from the coils on the farther side.
•This keeps the train in the center.
PRINCIPLE OF LATERAL GUIDANCE

13. “Maglev Train”
Gap Sensor
This attractive force is controlled by a gap sensor
that measures the distance between the rails and
electromagnets

14. “Maglev Train”
The train makes little noise
because it does not touch the
track and it has no motor.
Therefore, all noise comes
from moving air. This sound is
equivalent to the noise
produced by city traffic.

Advantages of Magnetic Levitated
Transportation System
 Maglev uses 30% less energy than a high-speed train traveling at
the same speed.
 Research has shown that the maglev is about 20 times safer than
airplanes, 250 times safer than conventional railroads, and 700
times safer than automobile travel.
 Maglev vehicle carries no fuel to increase fire hazard
 Despite the speeds up to 500 km/hour, passengers can move about
freely in the vehicles at all times.
 The materials used to construct maglev vehicles are non-
combustible, poor penetration transmitters of heat, and able to
withstand fire.

16. “Maglev Train”
Disadvantages of Magnetic Levitated
Transportation System
 Expensive to install
 Very complex computer system to control the thing requiring
specialist knowledge and maintenance .
 Complete lack of flexibility.
 Maglev trains would be limited to where maglev lines run.

Future Projects In India
 Projects are :
 Pune – Mumbai
 Mumbai – Delhi
 Mumbai – Nagpur
 Chennai – Bangalore – Mysore ( Speed will be
350kmph
and travel time 30 min)

18. “Maglev Train”
Applications
 NASA plans to use magnetic levitation for launching of
space vehicles into low earth orbit.
 The mining industry will also benefit from Maglev.
 Maglev fans provides superior performance, long life,
zero friction with no contact between shaft and bearing
 Analyzing food and beverages.
 Maglev heart pump

19. “Maglev Train”
Conclusion
o The Mag Lev Train: Research on this ‘dream train' has been going
on for the last 30 odd years in various parts of the world.
o The chief advantages of this type of train are : Non-contact and
non-wearing propulsion, independent of friction, no mechanical
components like wheel, axle.
o Maintenance costs decrease
o The Mag Lev offers a cheap, efficient alternative to the current rail
system. A country like India could benefit very much if this were
implemented here.
