3. Bullet train is a system of transportation that uses
magnetic levitation to suspend, guide and propel
vehicles from magnets rather than using mechanical
methods, such as friction-reliant wheels , axels and
bearings. Bullet train is a means of flying vehicles or
object along a guide way by using magnet to create
both lift and thrust, it lift only few inches above the
guide way.

4. HISTORY
The vision of maglev begin in early 20 th century
with two men Robert Goddard and Emirly
Bachelet. There dream is to develop a system
which is faster , reliable, efficient. Thus they
turned to electromagnets.

6. Why Maglev trains move so Quickly?

7. The bullet train moves so quickly because there
is no friction unlike the conventional trains.
Does it means the trains remain in air.
But how it is possible???

1. ELECTROMAGNETS
2.MAGNETIC LEVITATION

9. Magnetic levitation, maglev,
or magnetic suspension is a
method by which an object is
suspended with no support
other than magnetic fields.
Magnetic force is used to
counteract the effects of the
gravitational acceleration and
any other accelerations

11. • The concept of Levitation depends on the
phenomena of MEISSINER EFFECT.
• The MEISSINER effect is the phenomena in which
the magnetic field lines move away from the
material and acquire the property of Super
Conductivity.
• This is done by cooling the substance below the
Critical Temperature.
• The liquid nitrogen is used to cool down the
temperature of material.

12. Superconductivity is the phenomena of exactly
Zero electrical resistance and expulsion of magnetic
field occurring in certain materials when cooled below
a characteristic critical temperature.
Transition Temperature (Tc):
The critical temperature at which there
is change from normal
to superconducting and vive versa
is known as transition temperature

13. TYPE 1 Superconductor
• They are also called soft
superconductor.
• The critical field and transition
temperature is low.
• The change from normal state to
super conductivity state is normal.
• This show Messiner effect
completely.
• Example-Mercury ,Lead ,Tin.
TYPE 2 Superconductor
• They are also called hard
superconductor.
• The critical field and transition
temperature is high.
• The change from normal state to
super conductivity state is gradual.
• This does not show Meisinner
effect completely.
• Example-Vanidium , YBCO , BSCCO.

26. This system uses electromagnetic suspension
technology (EMS) and it works on the concept
that electromagnetic forces attract to a metal or
another electromagnet when they face each
other with the opposing polarities.
THIS IS
HOW IT
MOVES

27. THE EDS work on the principle of
SUPERCONDUCTIVITY as explained
before in messiner effect in which
the material is being cooled below
critical temperature

29. The system under the electrodynamic suspension
technology (EDS) and it works on the concept of
repulsive magnetic forces when electromagnets face
each other with the same polarities. The EDS system
uses superconductors cooled with liquid helium

30. The propulsion is achieved by
three phase synchronous
generator

32. COMAPRISON
BULLET TRAIN
• NO FRICTION=LESS
MAINTAINENCE
• NO ENGINE NO FUELS
REQUIRES.
• SPEED IN EXCESS OF 300
MPH
CONVENTIONAL TRAIN
• ROUTINE MAINTANCE
NEEDED
• ENGINE REQUIRES FOSSIL
FUELS
• SPEED UPTO 110 MPH

33. 1
• The trains
are virtually
impossible to
derail
because the
train is
wrapped
around the
track.
2
• Collisions
between trains
are unlikely
because
computers are
controlling the
trains.
3
• There is very
little
maintenance
because
there there is
no contact
between the
parts.

34. Less energy consumption
because has no rail track
friction.
Requires no fossil fuel which
harm the environment.
Less noise pollution since train never
hits the track.

35. On December 18, 2015 , India and Japan signed a
rupees 98,000 crore project to lay India’s first Bullet
Train network between commercial nerve centre of
Mumbai and Ahmadabad
Our Prime Minister Mr . Narendra Modi said that this step would
revolutionize the Indian railways and would also speed up Indian
journey into the future.

36. The BULLET TRAIN is one of the fastest mode of
transportation. The Bullet train is the one time
investment and it is friendly to environment too
.It also saves the time .The countries presently
having bullet train are Japan, Germany , South
Korea.
