Abstract Non-contacting magnetic bearing systems are known but some require the flow of electrical current even in the equilibrium condition and another known-system uses a control system in which current can produce detrimental changes in the existing field of magnetic force within the magnetic circuit. The present invention avoids these problems by arranging a control-current guide at each air gap between the magnetizable body and the pole-pieces of the magnet system. The direction of rotation of the control current in the leakage area of one air gap, in relation to the direction of the magnetic flux within the relevant air gap, is opposite to that of the control current in the leakage area of the other air gap at the same times. No currents flow during equilibrium conditions.
