FE-2100MQ miniature magnetic moment measuring instrument belongs to the 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 fluxmeters and Helmholtz coils to measure the magnetic moment, remanence, coercivity and maximum energy product of rare earth and permanent magnets. It can greatly save the measurement time of the quality data of magnetic materials, and is completely suitable for the rough classification and screening of a variety of magnetic materials.
PrincipleFE-2100MQ miniature magnetic moment measuring instrument belongs to FE-2100MQ rare earth permanent magnet material quality testing device plus miniature Helmholtz coil. Currently rare earth material manufacturers measure the quality of rare earth materials by using fluxmeters and Helmholtz coils to measure the magnetic moment, remanence, coercivity and maximum energy product of rare earth and permanent magnets. It can greatly save the measurement time of the quality data of magnetic materials, and is completely suitable for the rough classification and screening of a variety of magnetic materials.IntroductionThe FE-2100MQ miniature magnetic moment measuring instrument adopts a flux meter with a miniature Helmholtz coil. It is mainly used to measure the magnetic flux of a permanent magnet device under the condition of the coil. Multiply the coil constant to obtain the magnetic moment of the device. The size of the sample can be calculated material Br, Hcb and BHmax. Experiments have verified that the use of one-dimensional coils to test axially magnetized cylindrical, toroidal, and square-type rare earth permanent magnet samples can accurately test the total magnetic moment M (to be precise, Mz) of the material, and the material BH demagnetization curve is close to The straight line can accurately calculate the three important parameters of the magnetic properties of the material, Br, Hcb, and BHmax, so as to judge the quality of the material. It is well used for the transfer of the quality of rare earth permanent magnet materials between material companies and material users. Among them, the accuracy and repeatability of the magnetic moment test are far superior to the use of BH test equipment to test standard samples to transmit data. The high test efficiency can achieve full inspection of all magnetized samples, and timely discover device defects, while ensuring that the materials Judgement of magnetic energy product level.Key words:- Mini Magnetic Moment Measuring Instrument
