Richard F Post: Dynamically stable magnetic suspension/bearing system. The Regents of the University of California, Henry P Sartorio, John P Wooldrige, February 27, 1996: US05495221 (172 worldwide citation)

A magnetic bearing system contains magnetic subsystems which act together to support a rotating element in a state of dynamic equilibrium. However, owing to the limitations imposed by Earnshaw's Theorem, the magnetic bearing systems to be described do not possess a stable equilibrium at zero rotatio ...
