Claim:
1. An apparatus, comprising: a system longitudinal axis; a cylindrical rotor having a central longitudinal rotational axis, said rotor including a first planar semicircular permanent magnet and a second planar semicircular permanent magnet, wherein first flux of said first planar semicircular permanent magnet is pointed in a direction parallel with said rotational axis and toward a first end of said rotor and wherein second flux of said second planar semicircular permanent magnet is pointed in a direction parallel with said rotational axis and toward a second end of said rotor; and a first stationary shorted circular winding the plane of which is perpendicular to said system longitudinal axis, wherein the center of curvature of said circular winding is positioned on said system longitudinal axis, wherein upon rotation of said rotor, when a transverse displacement of said central longitudinal rotational axis relative to said system longitudinal axis occurs, said winding will experience a time-varying magnetic flux such that a current that is proportional to said displacement will flow in said winding.
