It would be made of a graphite layer, which allows for diamagnetic levitation, and a flex circuit to generate electromagnetic ...

Magnetic levitation, or maglev ... Once the initial magnetic field is established, cars made of diamagnetic materials float above the track, moving without the need for additional energy input.

The difference here is that rather than low-friction sapphire bearings, this motor uses zero-friction magnetic levitation using pyrolyzed graphite discs. The diamagnetic material hovers above a ...
