Diamagnetic levitation of pyrolytic graphite over monolithic NdFeB magnet

Recent developments in the technology of printing magnet field domains offer a whole new field of applications. Highly customised magnetisation patterns can now be generated which enhance significantly the magnetic properties and behaviour. Magnets with specific printed magnetic field patterns can also be used for enhancing diamagnetic levitation applications. This reported work demonstrates the diamagnetic levitation of pyrolytic graphite over a monolithic NdFeB cylinder magnet with printed magnetic field domains. Using monolithic magnets instead of magnet assemblies for diamagnetic levitation allows easier, faster and cheaper production of diamagnetic levitation tracks or diamagnetic bearings. Furthermore, one can build the diamagnetic levitation tracks, which otherwise are difficult or impossible to be realised using prior art technologies.
