This essay is on Magneticly Levitated Trains.... It explains basicly how they work as well as how they have a future in transportation because they are very efficiant.

Introduction The future of transportation lies with the Magnetic on the wholey Levitated, or magnetic levitation, train. It combines all the benefits of an plane and the benefits of trains to produce a Flying carry (2) maglev applied science was pioneered on Long Island New York in the 1960s by deuce Brookhaven National Laboratory scientists, James Powell and Gordon Danby... who employ super conducting magnets for MagLev trains (9). It is a project that has since been dropped by the US due to deprivation of government funding. However, it is a technology that is more or less at the school of commercial use in Germany and japan (the 2 major(ip) testing facilities) (4). There are 2 important types of levitation and propulsion which I will explain in this essay, (EMS) electromagnetic Suspension and ( explosive detection system) Electrodynamic Suspension. EMS is act as extremely close to the track (about 10mm), this makes it slightly unstable. EDS merely is put across much higher above the track (about degree centigrade to two hundred mm) making it most likely to be the organisation utilize on the first commercially active MagLev trains. Superconductor The chief(prenominal) problem with the MagLev concept is that it requires extremely concentrated magnets to bring up the train. For this reason superconductors were used, superconductors are materials which, when heated or cooled to a double amount, become extremely magnetic.

The next problem was creating address impelling units, the Japanese accomplished this: The unit that was used is called the SMS. The SMS uses liquid arouse nitrogen to keep the superconductor being used at the ne ar temperature. Because the nitrogen is con! tinuously being heated due to the event that it absorbs so much heat, it is cooled using refrigerated helium. (6) Levitating and Running the Train There are 2 systems used to levitate and direct the MagLev trains. EMS (electromagnetic suspention and EDS (electrodynamic suspention). EMS...
