Claim:
1. A support for a movable element, the support comprising: a stator element; a gravity compensator field inducing element mounted on the stator element, the gravity compensator field inducing element configured to apply a translational force, in a direction with at least a component parallel to the direction of gravity, to the movable element by controlling a magnetic field in a gap between the stator element and the movable element; and a plurality of torque compensator field inducing elements, separate from the gravity compensator field inducing element, mounted on the stator element, the torque compensator field inducing elements configured to apply a torque to the movable element by controlling a magnetic field in the same gap between the stator element and the movable element, the torque being about a first axis substantially perpendicular to the direction of the translational force applied by the gravity compensator field inducing element.
