| 英文摘要 | The search coil magnetometer (SCM) is a kind of magnetic sensors which is applied widely in oil and mineral explorations, earthquake monitoring, space research and so on. Also SCM is one of indispensable roles in EM exploration device. Funded by China's SinoProbe Plan, the SCM with high sensitivity for the Magnetotellurics (MT) is developed. In this article, the SCM with magnetic flux negative feedback structure is described. The chopper stabilized circuit is applied for removal of the 1/f noise in low frequency. The mu-metal core with high permeability increases the sensitivity of the SCM. The theoretical and test results show that the bandwidth of the SCM is from 1 mHz to 1 kHz, the noise level at 0.1 Hz is 1.5 pT/root Hz, at 1 Hz is 0.15 pT/root Hz, and at 10 Hz is 0.03 pT/root Hz, respectively. The length of the SCM is 96 cm, diameter is 60 mm, and the weight is less than 6 kg. The SCM presented here can meet the demand of the magnetotellurics (MT) method. |
