Electromagnetic Propulsion Technology Essay

Electro magnetised Propulsion technology is based on the concepts and applications of electromagnets to enable propelling of an object. This is perhaps the nigh researched and worked on areas of electric propulsion with greatest possible application in public transport as well as advanced aerospace propulsion arrangings.For public transport, its been a charismatic levitation technology which is similarly fill outn as maglev that has transformed the vary way of public transport. Electromagnetic Propulsion Technology based Magnetic levitation transport is a form of emigration that relies on electromagnetic force for suspension, focusing and propelling. This technology when applied for mass transit dust can enable transportation at cholecalciferol to 600 km/h (Bonsar, p1 Jahn & Choueiri, p134) .As a concept, magnetic levitation see was developed by a German Scientist Hermann Kemper and on Aug. 14, 1934, the patent was granted. But it was in Britain, worlds first magnetic lev itation service was introduced as a link between two terminals at Birmingham airport. The distance was of 400 meters with top speed at around 10-mph.In Germany, the TRANSAPID project connects Berlin and Hamburg. The train will move with a speed of 292 kph and would address the distance of 292 km in flat 60 minutes. In Japan, the advancements have led to the feasibility of moving trains at a speed of 500 kph and on a 7-km test track began in Miyazaki Prefecture, the manned two-car vehicle has been tested and found to register a speed of 400.8 kph in 1987 and a maximum speed of 531 kph in a manned vehicle run on celestial latitude 12. Again in 1999, the train attained a maximum speed of 552 kph in a manned vehicle run (Maglev, p8).Maglev follows the system levitation based vehicular movement on the pull back way while using electromagnetic forces between super conducting magnets on the vehicle and coils on the ground. This enables the train to move or float about 10 mm above the gu ide way on a magnetic field. The train as full-length is propelled by the guide way and hence thither is no on board engine to pull the train. The whole pulling is enabled through the switching of magnetism.Its canonic principle could be understood with the help of magnets. As it is widely known that in case of magnets, you know that opposite poles attract and like poles repel. This principle of attraction and repulsion actually forms the basics behind electromagnetic propulsion based Maglev technology. Electromagnets are used in the above menti angiotensin-converting enzymed technology and temporary magnetic pull is created and objects are attraction through a small magnetic field. The three vital components to this system areA large electrical power sourceMetal coils lining a guideway or trackLarge guidance magnets attached to the underside of the trainIn the above mentioned list of components, one can figure out that the train doesnt need any engine and hence this is the aroun d important difference between the maglev trains and other conventional trains. The train as a whole is not pulled in a particular direction rather they are propelled and guided in the magnetic field created by electrified coils in the guideway walls and the track (Bonsor, p2).ConclusionAs it has been already mentioned, Maglev is the short for magnetic levitation according to which floating and guiding of trains is enabled as per the principles of magnets. Maglev has its own compensate of advantages as well as disadvantages. The primary advantage of a maglev train is that of maintenance. As the train floats along and there is no contact with the ground and also there are no moving parts, the possibilities of any wear and fleece get reduced. The trains as well the track would rarely need any maintenance and hence the higher(prenominal) cost of installation gets compensated in long run. Apart from this, the other important advantage is the bring reduction of friction and noise whic h actually translates into high speed and extremely fast mode of transportation (Maglev, p 28).Now comes the disadvantages Maglev guide paths are more costly than any conventional railways system when installation comes into picture. This disadvantage gets amplified with the fact that Maglev system requires a complete new set of foundation. The railways infrastructure available for usage is of no use for implementing Maglev and hence a totally new set of system would be implemented. The conventional system would lose its utility and couldnt have a rough-cut existence with maglev (Maglev, p 28).Hence, after a very careful and thorough research, the final finding of fact is that the Principle of Magnetic Levitation when applied for mass transit would transform the way people move in the future and might provide an able substitute of all expensive air transport.ReferenceBonsor, K.
