| Abstract: | 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. |
