| titleOfInvention | A low-noise induction magnetometer for weak alternating magnetic field magnitude transfer |
| abstract | The invention relates to a low-noise inductive magnetometer for weak alternating magnetic field magnitude transmission, belonging to the technical field of magnetic field measurement. The extraction circuit is optimized to make the noise floor of the inductive magnetometer probe reach 50fT/Hz 1/2 @10Hz, and the measurement uncertainty of the inductive magnetometer can reach 1pT (k=2). The weak magnetic signal detection ability of the current metrology-grade inductive magnetometer is insufficient. The new inductive magnetometer can not only improve the sensitivity of the original metrology-grade inductive intensity meter probe, reduce the background noise, and significantly improve the signal-to-noise ratio of the inductive magnetometer host, but also has good temperature stability and probe frequency. The wide response range is more conducive to the realization of magnetic signal waveform fidelity, time domain analysis and spectral domain analysis. |
