Abstract：Measuring the magnetic properties of soft magnetic material parameters are the key to ensuring the quality of the device, guiding the research and development of new magnetic materials. Conventional ballistic galvanometer method are defined in the relevant international and national standards, but the use of mechanical switches and ballistic galvanometer may bring non-transient error, and it requires the experienced and professional staff to do the measurement, while measurement process is of low efficiency. Traditional method is gradually eliminated by adopting electronic switches and digital (analog) measurement device flux meter designed replaced, and by software to control the entire testing process. The definition of basic magnetization curve, basic hysteresis loop of soft magnetic material is proposed. By studying the DC magnetic measurement method and hardware, satisfactory result is obtained, promoting the development of static magnetic measurement and providing a reference for improvement of related standard.
