Magnetic properties of the isotropic and anisotropic NdFeB magnets obtained by the Current-Applied Pressure-Assisted (CAPA) process from a melt-spun NdFeB powder were investigated using B-H loop analyser. The coercivity of the isotropic magnets is sensitive to the applied pressure in the CA-pressing and increases with increasing the pressure. The remanence of the anisotropic magnet increases with increasing the degree of deformation, and it results in the increase of a maximum energy product. The best magnetic properties of the isotropic and antistropic magnet are Br=8.7 kG, iHc= 16.9 kOe, (BH)max = 16.5 and Br=13.6 kG, iHc =10.9 kOe, (BH)max = 44.2 MGOe, respectively.
