Claim:
1. An apparatus, comprising: a rotor; a stationary support structure; a first plurality of (Halbach) HB arrays attached to only one of said rotor or said stationary support structure; and a first array of closed circuits attached to only the one of said rotor or said stationary support structure to which said first plurality of HB arrays is not attached, wherein said first plurality of HB arrays and said first array of closed circuits face each other and are separated by a gap, wherein said gap is characterized by a first boundary next to said plurality of HB arrays and a second boundary next to said array of closed circuits, wherein only one of said first boundary or said second boundary is circular and only the other of said first boundary or said second boundary is elliptical, wherein each Halbach array of said first plurality of HB arrays has a wavelength that is less than said gap, selected to produce, when said rotor is rotating, repelling forces that increase exponentially when said first plurality of HB arrays is displaced laterally with respect to said first array of closed circuits.
