    Magnetic levitation a.k.a. maglev originated in Japan and now the United States is going to start adopting its technology.  It functions by hovering an object off of another object.  Both of the objects must have repelling magnets in them to create a hover.  Magnetic trains are what have been using the maglev technology.  The train tracks are T-shaped so that the train can wrap around it and not fall off.  Magnets are on all sides so that if one set of magnets fail they still have three other sets of magnets to keep everything moving.
