A variety of magnetic properties have been found, such as ferromagnetic response well above room temperature and structural changes linked to magnetic anisotropy. In this paper, theoretical as well as experimental work performed on these materials to date is critically reviewed, in terms of methods used, results acquired, and conclusions by: Therefore, I am looking for a material, F, to place between M and S to prevent S from getting affected by M:s magnetic field either by somehow leading the magnetic field from M around S or to block the field from reaching S (is that even possible?).
Furthermore, F itself is NOT allowed to be attracted nor repelled to M by its magnetic field. The goal of this research was to investigate the mechanical properties of injection molded Nylon and PPS-based Nd-Fe-B type development of new Nd-Fe-B type magnetic materials and the advancement of near-net shape injection molding processes for magnetic component manufacturing have driven the needs to evaluate the mechanical properties.
