Utilising the relatively strong paramagnetic properties of oxygen, with the aid of the special magnetic filter construction according to the invention having filter elements comprising magnetisable material, the oxygen portion of an oxygen-containing gas mixture flowing through these elements is greatly enriched. Different embodiments are proposed for the construction of the filter elements, that is to say a slotted sheet metal construction of permanently magnetisable material and a package construction of non-permanently magnetisable yoke sheet metal packages and permanently magnetisable longitudinal bridges. Diverse embodiments of these fundamental solutions according to the invention achieve further technical advantages which are aimed both at an increase of the filter activity and at specific applications. The increase of the activity in the enrichment of oxygen in the filtered gas mixture is achieved, inter alia, by the proposed measures for improved intake by suction of the oxygen from the external region of the magnetic field. The further proposals aimed at particular applications deal with, inter alia, the use of the magnetic filter in internal combustion engines in order to reduce the pollutant content of the exhaust gases of the same.
