The ic and electrical properties of the ML, which lack of study in literatures, are researched by takingFe57Ni43for example. Besides the material characteristicsof Fe57Ni43, the ML ic field characteristics are studied by a 3-D finite element modelestablished by ANSYS, and the echo electrical signal isanalyzedby establishingelectronic information systembased on DSP. The results achieved in this paper will provide a theoretical basisfor the ML to
