An instrument that measures the magnitude and/or direction of a magnetic field. A magnetometer can be either a scalar instrument that measures the magnitude of the total field or a vector instrument that measures one or more vector components of the field. Some magnetometers are relative devices that are calibrated with respect to a known field. Others are absolute devices that yield magnetic-field values without calibration. Arrays of magnetometers can be configured as gradiometers that suppress or enhance far-field magnetic sources while enhancing or suppressing near-field sources. Magnetometer technology is available for detecting a range of magnetic fields (Fig. 1).
