Abstract
An apparatus, and methods of making and using the apparatus, including at least a first path of magnetic flux perpendicular to and penetrating a first plane in space; preferably, a second path of magnetic flux perpendicular to the first plane and having a gradient such that no net flux passes the first plane; and a passive first null flux coil adjacent to the first plane; whereby when one of the first null flux coil and a combination of the paths is moving, the first null flux coil and the paths, combinatorily, are magnetically induced into alignment with respect to the first plane.
