., Ltd., Changsha 410205, China) Abstract: Magnetic field induction sensors have been the bottleneck in the development of electromagnetic devices in China. In abroad, the natural geomagnetic variations are mainly measured by magnetic field induction sensors in magnetotelluric methods. According to the characteristics of the natural geomagnetic variations in audio-frequency band and the basic......
