Design and Analysis of Maglev Trains

For decades, conventional trains, a major source of land transportation, have served people around the world. But the issue is that conventional trains create too much noise and pollution. Also the world is becoming a smaller place for business. As such, people travel longer distances, more often, and so there are longer travel times. This leads to too much fossil fuel consumption and that rate is increasing. That is why some people say, in the next 50 years, that the fossil fuel resource is going to run out. Faster fuel consumption also leads to increased pollution in the environment. So in short, we need travel times to be made shorter and we need a renewable energy source which is clean. A method of supporting and transporting objects or vehicles which is based on the physical property that the force between two magnetized bodies is inversely proportional to their distance. By using this magnetic force to counterbalance the gravitational pull, a stable and contactless suspension between a magnet (magnetic body) and a fixed guide way (magnetized body) may be obtained. In magnetic levitation (Maglev), also known as magnetic suspension, this basic principle is used to suspend (or levitate) vehicles weighing 40 tons or more by generating a controlled magnetic force. By removing friction, these vehicles can travel at speeds higher than wheeled trains, with considerably improved propulsion efficiency (thrust energy/input energy) and reduced noise. In Maglev vehicles, chassis-mounted magnets are either suspended underneath a ferromagnetic guideway (track) or levitated above an aluminum track.
