Magnetic mixed‐matrix membranes (MMMs) are fabricated using polysulfone (PSf) and iron oxide (Fe) for O 2 /N 2 separation. The effects of Fe nanoparticle size and content on the performance of the membranes are investigated using a novel gas permeation unit in the presence of various magnetic fields. The results indicate that the O 2 permeation is improved by adding Fe nanoparticles into the PSf matrix regardless of the particle size. Furthermore, the selectivity of PSf and PSf‐Fe membranes is considerably enhanced by applying a magnetic field during the permeation experiments. The O 2 permeability and O 2 /N 2 selectivity of PSf‐Fe50 MMMs in the presence of a magnetic field are higher than those of neat PSf membranes.
