摘要： A loss prevention device includes a magnetometer and a processor operatively coupled to the magnetometer. The magnetometer is configured to measure intensities and directions of one or more maxima in a magnetic field, the one or more maxima including at least a first maximum from magnetic north of the Earth, wherein a first intensity and a first direction are associated with the first maximum. The processor is configured to ignore the first intensity and the first direction associated with the first maximum and to determine whether the one or more maxima includes a second maximum distinct from the first maximum.
