Pyrolytic graphite levitating over a neodymium magnet array

2005

A roughly 6 mm chip of pyrolytic graphite floating over four 5 mm neodymium cube magnets whose poles alternate in a checkerboard. Pyrolytic graphite is diamagnetic enough to hover over ordinary permanent magnets at room temperature, with no power and no cooling - the cheapest possible demonstration of Faraday's effect.
