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.

FE-2100MQ miniature magnetic moment measuring instrumentAdoptmagnetic flux meterWith the configuration of microHelmholtz coil, mainly used in the magnetic flux measurement of permanent magnet devices under the condition of the coil, multiplied by the coil constant to obtain the magnetic moment of the device, for the regular size of the sample can calculate the material Br, Hcb and BHmax, etc. It has been verified by experiments that the total magnetic moment M (Mz to be exact) of the material can be tested very accurately by using one-dimensional coils to test axially magnetized cylindrical, circular and square rare earth permanent magnet samples. By using the BH demagnetization curve of the material to be close to a straight line, the three important parameters Br, Hcb and BHmax of the magnetic characteristics of the material can be calculated more accurately, thus judging the quality of the material, it is well used in the quality transfer of rare earth permanent magnet materials between material enterprises and material use enterprises. The accuracy and repeatability of magnetic moment test are far better than those of BH test instrument to test standard sample transfer data. The high test efficiency can realize full inspection of all magnetized samples, find defects of devices in time, and ensure the judgment of material magnetic energy product grade.
