Introduction of Micro Magnetic Steel Magnetic Moment Measuring Instrument

Introduction of Micro Magnetic Steel Magnetic Moment Measuring Instrument

FE-2100MQ miniature magnetic moment measuring instrument belongs to FE-2100MQ rare earth permanent magnet material quality testing device plus miniature Helmholtz coil. At present, rare earth material manufacturers measure the quality of rare earth materials by using flux meters and Helmholtz coils to measure the magnetic moment, remanence, coercivity and maximum magnetic energy product of rare earth and permanent magnets. It can greatly save the measurement time of the quality data of the magnetic material, and is completely suitable for the rough classification and screening of a variety of magnetic materials.

Analysis of nondestructive testing of permanent magnet materials using the pole head embedded coil method

Analysis of nondestructive testing of permanent magnet materials using the pole head embedded coil method

Using the electromagnet pole surface embedded coil method to test the permanent magnet material is an application-oriented technical scheme designed according to the BH characteristics of the current industrial test permanent magnet material. Since the actual size and shape of the sample do not need to be considered during the test, there is no need to wind or set a fixed B/J coil on the magnet, and only the test sample needs to be completely covered on a coil embedded in the pole head, the test is convenient, The repeatability is good, and there is a certain market prospect.
