Abstract :
The fluxgate sensor presented consists of a hairpin-shaped nonmagnetostrictive amorphous metal ribbon which carries the excitation AC current. Even harmonics are induced in a surrounding coil, which can be used both as a pickup coil and as a field compensation coil. The principle of operation is similar to that of a traditional ring-core system except that the core itself carries the excitation current. The sensor competes favorably with traditional fluxgate sensors with respect to simplicity, miniaturization, signal level, and noise level
