Oxygen and nitrogen in the air have different magnetic properties in a magnetic field. Oxygen and nitrogen are paramagnetic gases and diamagnetic gases, and the magnetizing force received in a gradient magnetic field is in opposite directions. Based on the magnetization theory and simulation experiment analysis, this paper uses the difference in the direction and magnitude of the magnetization force of oxygen and nitrogen in a gradient magnetic field to study the force state of oxygen and nitrogen molecules in the input air in a gradient magnetic field and the oxygen mass fraction of the output gas to explore effective ways to obtain oxygen-enriched gas. The results of this study can provide oxygen-enriched gas for operations such as oxygen-enriched combustion technology and sewage treatment engineering, and improve operational efficiency.
