Anybody think they could show me how to make an electromagnetic MagLev track? as simple as possible please.

i want to do a science fair project on the matter but im going to have some fun with it and make one into a nascar track ! haha

get one of those cars that go around a track (when you squeeze the trigger, the car accelerates) then figure out how to levitate it with opposing magnets

if that's too much..
then just get two magnets and show how maglev works
