The method for analyzing force and moment characteristics of magnetic suspension providing levitation of diamagnetic bodies of various nature and shape is theoretically developed. This method is based on calculating the interaction energy of a body with the supporting field of arbitrary configuration as a function of the body displacements with respect to the center of the suspension. Necessary and sufficient conditions for conservative stability of the equilibrium state were found, and the stability region for arbitrarily shaped diamagnetic bodies was determined. Practical analyses of power characteristics of the suspension of diamagnetic bodies are presented.
