Pyrolytic carbon
Videos
Pyrolytic carbon is a material similar to graphite, but with some covalent bonding between its graphene sheets as a result of imperfections in its production.

Magnetic levitation or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational

…pyrolytic graphite has a relative permeability of 0.9996, whereas bismuth has a relative permeability of 0.9998 (table). Few materials can be made to magnetically levitate stably above the magnetic field from a permanent magnet. Although magnetic repulsion is obviously and easily achieved between any two magnets, the shape…
Electromagnetic levitation device that includes a permanent magnet for primary force (big dark-gray ring), and electromagnets for stabilization (copper coils in the center)
Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used
