Diamagnetism with Pyrolytic Graphite Levitation

Sail a magnetic sea

Diamagnetic levitation with pyrolytic graphite

Sail a magnetic sea with diamagnetic levitation. Diamagnetism causes pyrolytic graphite to levitate.  This floats around with less than 1 mm gap above a 13 x 13 array of 5 mm magnets.  The north poles are marked as black and the square sheet is 45 mm a side and 0.5 mm thick (20/1000 inch). The video shows the sheet sliding around without friction when I tilt the base slightly.

Magnetic Repulsion Demo

Magnetic repulsion
Magnetic repulsion demo. You can’t push them together. This is a popular demonstration of magnetic repulsion. You try to bring the North poles of these magnets together but physically can’t. You start feeling the invisible field at about 10 cm and it becomes stronger than you are at about 2 cm. It is a spooky feeling.

Creatures on my hand

Flying bullant is one of the creatures on my hand in this page

Photos of local creatures on my hand.  This is a winged bull ant (Myrmecia gratiosa). It is vigilant and aggressive with a very painful sting but this one seemed happy to walk on my hand while I took snaps with my other hand.
