A magnetic suspension system is disclosed including a fixed member and a movable member, each of said members having magnetically permeable pole pieces defining a magnetically permeable gap therebetween and means for producing a suspending magnetic field across said gap. Apparatus for applying an electrically generated force between said members is provided which includes an electrical coil mounted on one of the pole pieces and in the gap and having at least a portion of the conductors thereof oriented at right angles to the magnetic flux fields in the gap, and means for supplying a current through the coil means thereby to distort said magnetic suspension flux field in the gap whereby said other pole piece in tending to follow the flux field produces a force on the suspended member proportional to the coil current.
