Spin-stabilized magnetic levitation

Spin-stabilized magnetic levitation is a phenomenon of magnetic levitation whereby a spinning magnet or array of magnets (typically as a top) is levitated via magnetic forces above another magnet or array of magnets, and stabilised by gyroscopic effect due to a spin rate that is neither too fast, nor too slow to allow for a necessary precession. The phenomenon was originally discovered through invention by Vermont inventor Roy M. Harrigan in the 1970s.
