The document discusses the history and principles of maglev trains. It explains that maglev trains use electromagnetic forces and feedback loops to levitate above the track without touching it. This allows maglev trains to move at very high speeds with little friction. The document provides examples of existing maglev systems like the Transrapid in Germany and the MLX01 in Japan. It also discusses potential applications of maglev technology in India, including a proposed high-speed line between Mumbai and Delhi.

What is Levitation ?

4.  The first commercial Maglev "people-mover"
was officially opened in 1984 in Birkingham,
England.
 It operated between Birkingham International
Airport and Birkingham International railway
station.
 It ran at 42 km/h (26 mph) .

5.  They work on a basic principle of magnetism
i.e.
“LIKE POLE REPEL EACH OTHER AND UNLIKE POLE
ATTRACT EACH OTHER.”

9.  The attraction from a fixed strength magnet
decreases with increased distance, and increases at
closer distances. This is unstable. For a stable
system, the opposite is needed, variations from a
stable position should push it back to the target
position.
Basic Problem in Levitation
HISTORYINTRO PRINCIPLE WORKING

10. Stable magnetic levitation can be achieved by measuring the position and speed
of the object being levitated, and using a feedback loop which continuously
adjusts one or more electromagnets to correct the object's motion, thus
forming a servomechanism.

controlled using eddy currents, diamagnetic materials
or superconductors

20. Magnetic levitation is a very promising field
which guarantees faster transport, lesser
pollution, future energy potential &
employment generation compatible with MAKE
IN INDIA philosophy
The results showed that Maglev can be
conveniently considered as a solution for the
future engineering needs of the country.
