Zusammenfassung:The apparatus (50) includes an enclosure (24) having the wall (26) defining an interior and an exterior of the enclosure (24). The layer (52) of the highly magnetically permeable material is located closer to the interior of the enclosure (24) than is layer (54). The background field magnetometer (56) is positioned within the enclosure (24). An electrical coil structure (62) is made to provide the most complete cancellation of a particular background magnetic field.
