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.
