Evaluation of the Generated Magnetic Field from Coaxial Circular Flat Spiral Coil Integrated with Spark Plasma Sintering Technique for Sintering M-Type Based BaFe12O19

This paper introduces a new spark plasma sintering technique that can order crystalline anisotropy by the coaxial flat spiral coils which have been designed, modeled, and installed to work in coupled with the Spark Plasma Sintering (SPS) as a new sintering method called In-situ magnetic-anisotropy spark plasma sintering (MASPS) which has been used to produce anisotropic magnets by aligning the grains of the sintered powder. The two spiral coils have been connected to the cathode and anode of the SPS machine. The magnetic field generated from the coils has been designed and simulated using ANSYS MAXWELL software, and experimentally the field was measured manually using the gauss meter instrument. The excitation currents are 150, 200, 250, 300, and 350 A. Based on the results obtained the maximum magnetic field intensity and strength, at exciting currents of 150, 200, 250, 300, and 350 A are 3.0859 � 104 4.115�104, 5.1432�104, 6.1718�104, 7.2005�104 A/m, and 37.327, 49.769, 62.211, 74.653, and 90.400 mT respectively. © 2023 IEEE.
