1. A moving coil motor, comprising:

  • a fixed frame;

    a movable member supported by the fixed frame for movement in at least one degree of freedom with respect to a nominal plane;

    a magnet means for creating a generally axisymmetrical magnetic field having a magnetic axis substantially orthogonal to the nominal plane of the movable member;

    at least one electrically conductive element on the movable member, positioned about the magnetic axis and configured such that current flow through the electrically conductive element interacts with the magnetic field of the magnet means to create Lorentz forces to move the movable member in one or more degrees of freedom.
