ABSTRACT:
At least one set of two nested magnetic arrays is provided, each nested magnetic array having an outer magnet, a middle magnet, and an inner magnet. The outer magnet has a magnetization pointing in an at least partially axial direction. The middle magnet has a magnetization substantially perpendicular to the magnetization of the outer magnet. The inner magnet has a magnetization directed substantially anti-parallel to the magnetization of the outer magnet. The apparatus also includes at least one electrically conductive coil positioned at least partially between the two nested magnetic arrays. At least one substantially magnetically permeable object is positioned at least partially between the two nested magnetic arrays. A rod is integral with the substantially magnetically permeable object.
