Small scale models which levitate diamagnetic materials such as this haven't existed for the classroom, until now! It is only recently, with the creation of artificial neodymium magnets and artificial pyrolytic graphite, that the effects can finally be easily demonstrated. Diamagnetism is a very interesting and promising phenomenon in which macroscopic objects can be made to float under their own influence. Both diamagnetism and paramagnetism remind us of the connection that exists between electricity and magnetism, and furthermore of the fact that all matter is made of moving electric charges. The Diamagnetic Levitator makes for a great classroom demo!
A small wafer of "pyrolytic" graphite provides us with the best demonstration of "diamagnetic levitation." To be "diamagnetic" means to always be repelled by a magnet.
