2. BACKGROUND
 In 1966 Danby and Powell proposed an EDS system
for high-speed transportation using super conducting
magnets with a “null flux” suspension.
Subsequent researchers in the U.S., Japan, Germany,
UK and Canada have developed further innovations
(such as ladder type guide way for increased lift
efficiency), but there are still a number of technical
problems that needed resolution.

4. CURRENT DETAILS OF EMSS
There are three primary types of Maglev technologies:
superconducting magnets ( electrodynamic
suspension)
feedback controlled electromagnets
(electromagnetic suspension)
Newer potentially more economical system using
permanent magnets Inductrack.

14. COMMENTS
As the current ‘u’ increases the distance ‘x’ decreases.
As the current increases the magnetic force F
increases causes the movement of the ball towards
the coil.
The damper absorbs the oscillations as shown in the
Result 2.

15. CONCLUSION
An approach of the magnetic suspension system has
been presented. The simplified mathematical model has
been developed.
The EMSS has the ability to give much smoother
ride than any luxury sedan, and less roll and pitch
than any sports car .
