Research on the difference in magnetic measuring results and mechanism analysis in soft magnetic stainless steel between the ring samples and bar samples
With the increasing demand for the magnetic properties and overall performance of soft magnetic stainless steel in the field of automatic control industry,the measuring of magnetic properties of soft magnetic stainless steel is becoming increasingly important.First,we introduced the initial magnetization curve and normal magnetization curve of soft magnetic material in this paper.Then we compared the measured magnetic properties of the ring sample and the bar samples of the same product,as the measuring methods for test the magnetic properties of soft magnetic materials specified in the standards includes the ring sample method and the permeameter methods(using bars,rods,and other appropriate specimens).It is believed that this difference is a common phenomenon in bar and line samples.Moreover,the reasons for this differences are discussed,and the possible methods have to be taken in the future measuring are analyzed in details.Furthermore,due to the limitations for the testing method,only when reasonable methods are taken,then the measuring results can be accepted both by the supplier and the user.
