I am doing a project for my physics course....I have to design a device that uses electromagnetism. I'm thinking of doing something "different" rather than the boring bells/radios etc.. Would a small-scale model of a maglev train be feasible in everyone's opinion? I am planning to build a track out of a ,metal shaft wrapped with wire connected to a battery, and the train will be a long piece of wood with magnets attached to the underside. Would this work in levitating the magnets and wood? I raelize that the main problem is stability; I need to keep the "train" from tipping over so I plan to build "walls" on either side of the track that stabilize the train like this: http://www.tuat.ac.jp/~nagaimu/main_e/researches_maglev_icon.jpg Would this work? How powerful do the batteries need to be? do I need two parallel tracks or one?
