Magnetic levitation demonstrated using a Dremel tool spinning a magnet at 266 Hz. The rotor magnet is 7x7x7 mm3 and the floater magnet is 6x6x6 mm3. This video show the physics described in the work ...
The scientists chemically coated each graphite particle with a layer of electrically insulating silica. Polyethylene glycol (PEG) helps silica bind to the surface of the graphite. The coated graphite ...
