Abstract

This article consists of two parts. First part is a short review about the role of magnetic phenomena in natural environment, human surroundings, and his activities such as science, engineering, and medicine. The second part of the article presents a set of experiments, their results, and data obtained in a static homogenous magnetic field, generated by a pair of permanent magnets and outside it. Adsorption chromatographic systems were investigated: as chromatographed substances – polyaromatic hydrocarbon (PAH), as stationary phase – silica gel 60, as monocomponent mobile phases – n‐hexane, n‐heptane, n‐octane, and benzene were used and binary mobile phases n‐hydrocarbons – benzene. Magnetic field influences retention and efficiency of investigated chromatographic systems. Experimental data analysis (R~F~, N) allows us to propose some explanations of the differences between experiment results performed in induced magnetic field and outside it, and in consequence on the changes in the interfacial phenomena induced by field presence.
