Abstract
An apparatus for nulling a magnetic field within a nulling region in an external ambient magnetic field comprising a plurality of separate magnetic field generating elementsare located at separate respective locations surrounding the nulling region for generating respective nulling magnetic fields extending into the nulling region. A plurality of magnetic field sensing elementsare positioned at a plurality of respective separate locations within the nulling region for sensing respective values of the magnetic field within the nulling region. A feedback control unitcontrols the values of the respective nulling magnetic fields generated by each of the plurality of magnetic field generating elements in response to values of the magnetic field sensed by the plurality of magnetic field sensing elements by driving the magnetic field generating elements with respective electric currents that reduce the magnetic field values detected by respective magnetic field sensing elements to values not exceeding a pre-set threshold value corresponding to a pre-set nulling of the magnetic field within the nulling region.
