Abstract
A system includes a plurality of magnetometers that are each configured to generate a vector measurement of a magnetic field. The system also includes a central processing unit that is communicatively coupled to each of the magnetometers. The central processing unit is configured to receive from each of the plurality of magnetometers the respective vector measurement of the magnetic field. The central processing unit is further configured to compare each of the vector measurements to determine differences in the vector measurements and to determine, based on the differences in the vector measurements, that a magnetic object is near the plurality of magnetometers.
