摘要
弱磁性材料磁化率的数值很小,精确测量非常困难。在磁极头设计、励磁电路及计算机在测量中的应用等各方面进行研究,对传统的法拉第磁天平法加以改进,大大提高测量精度。
The susceptibility of weak magnetic substance is difficult to be precisely measured, due to its very small value. We improve the traditional method of Faraday magnetic balance, through the study on the design of magnetic tip and excitation circuit and the application of computer, and thus the measurement accuracy is increased greatly.
