| Abstract: | A coil measurement system has been designed to measure the magnetic induction intensity of the weak magnetic field generated by hypervelocity impact. Coil designing, equivalent circuit analysis, and the choice and function of the differential operational amplifier were expounded. The influence on measurement frequency of self-integration resistor was explored in theory. Finally, weak magnetic field signals generated by hypervelocity impact were obtained through experiments, and the recorded signals were smooth, which showed that the measurement system had a good anti-interference performance. |
