In this paper, it is suggested that 'spokes' that appear in Saturn's rings at the equinoxes consist of grains of silicates that have been coated in pyrolytic carbon through the process of chemical vapour deposition. Pyrolytic carbon is a highly diamagnetic substance and as such can levitate above a sufficiently strong magnetic field due to a repulsive force. The 'spokes' also consist of ice particles as ice is also a highly diamagnetic substance. The photoelectric effect can be used to explain why the silicates coated in pyrolytic carbon return back to the main ring structure when exposed to sunlight of a specific frequency ie they become paramagnetic and thus are attracted towards the magnetic field emanating from the main ring structure. It is also suggested that Saturn's rings always have 'spokes'. They are only visible however when a favourable viewing angle is allowed, which is dependent on the angle of the sunlight hitting Saturn's rings.
