levitating train experiment

Experiments with magnets interacting with other magnets Levitating Train Description: This is a great demonstration of like poles repelling each other. We have a platform which floats above a pair of magnetic tracks, and can be gently pushed to one end or the other. This is similar in concept to the MAGLEV trains which are being worked on in Germany, Japan and France. Construction: The tracks are simply two magnet strips, each measuring about 24" long, 1/2" wide, 1/8" thick, with their North side facing up. They are placed about 1/8" in from the edges of a piece of 3/4" thick wood shelving (with a white melamine surface) base, 24" long and 4" wide. Ends and a back wall are attached to the base, about 3" tall. The front of the base has a Plexiglas wall attached to it, so that you can see the train platform float above the tracks. The train platform is made of foamcore board, 3 and 7/8" wide by 6" long and 1/4" thick.
