    摘要: In one aspect of the present invention a method of determining a distance to a ferrous material comprises providing a plurality of magnetometers spaced at varying distances from a ferrous material, detecting a ferrous material with each of the plurality of magnetometers individually, establishing one of the plurality of magnetometers as a primary magnetometer, obtaining sensor readings from each of the plurality of magnetometers, forming a first ratio of the differences in the sensory readings of the primary magnetometer to the sensory readings of the other magnetometers, forming a second ratio of the differences in inversely cubed distances to the ferrous material from the primary magnetometer to inversely cubed distances to the ferrous material from the other magnetometers, setting the first ratio and the second ratio equal to each other, and calculating the distance to the ferrous material from the plurality of magnetometers.
