The probe of portable fluxgate magnetometer is composed of three fluxgate sensors (D, H, Z) orthogonal to each other. There are magnetic compensating coils around H and Z sensors, which can widely compensate the magnetic fields in the directions of H and Z component. The fluxgate sensors measure the vector values of geomagnetic field and magnetic interfering field projected on their components. The entire system is used to measure the magnetic field intensity changes of any spot. There are two ways for the output of magnetic field intensity measurement data: 1demonstration on an analog dial; 2collection, storage and transmission by a data collect system.
