The parameters of magnetic characteristic play an important role in products’ performances. For laboratory construction, this paper develops a static magnetic parameter manual measurement of soft magnetic materials system. “MCS-51 SCM” system is the core of the hardware. A magnetic circuit is designed and the magnetic current is given by nine series fixed resistances controlled by the switch and constant voltage source; In the testing of the sub-circuit design, induction EMF is transferred into SCM after wave transform, absolute strike and A/D conversion. The magnetic induction intensity B can then be obtained by calculation. In the software design, both C and assembly language are applied to design the procedure module of data collection, procession, storage and test result display. Modular programming entrusts the design the features of strong readability, easy maintaining and convenience upgrading. The developed prototype was tested in the laboratory. Results show that targets of this static magnetic measurement are achieved. The demand for education purpose is also met.
