Gregory Zizza Science Project Essay Maglevs Maglevs Magnetically levitated trains maglevs may be the transportation of the future because of their many advantages on modern transportation we use today Maglevs are trains that run on magnets in a certain way so that they are equally levitated They are a lot better than the trains we use today and run almost as fast as an airplane 320 mph Their maintenance is about 10 times less expensive than the trains today Since a maglev has no wheels to run on a track the tracks cant get worn out and have to be repaired Also these trains run on magnets and therefore do not produce pollution making them much more environmentally safe There are two types of maglevs a superconducting maglev and an electromagnetic maglev Electromagnetic ones will most likely be used more than the superconducting ones How Things Work Electromagnetic maglevs are faster and have easier formulas than superconducting maglevsWorld Book An electromagnet is a direct magnetic field produced by an electric current where it can be turned on and off because of the close relationship between electricity and magnetism Therefore the train runs along a guide rail supplied with electromagnets all along it The electromagnets can be turned on and off by switching the electricity running through it on and off In order to know when to turn on and off certain magnets there has to be feedback Feedback is what shows the current status off the trains stability and from that the controller of the magnets can adjust them so that the trains stay on a stable equilibrium From this one can conclude how the train worksHow Things Work The electromagnetic maglev rides along on a guide rail with electromagnets of the opposite pole that is on the train itself The bottom of the train wraps itself around the bottom side of the rail When the magnets are turned on
