The effect of the magnetic field on the physicochemical and tribotechnical properties of traditional lubricants and innovative nanostructured magnetic oils and liquids is considered. The reasons for changing these properties are analyzed. It is shown which factors primarily affect the polarizability of oils and the absorption of electromagnetic radiation. Methods of dielometry and infrared spectroscopy were used to evaluate the physicochemical properties. The integral effect of the magnetic field on the friction process of surfaces lubricated with traditional non-magnetic and magnetic oils was studied on an end friction machine. It is concluded that there is a significant change in individual physico-mechanical and chemical properties of magnetic lubricants under the influence of a magnetic field. A magnetotribological effect has been established, consisting in the influence of a homogeneous magnetic field on the lubricating properties of magnetic oil. The effect of homogeneous magnetic fields on the anti-wear properties of the oil is described. It is concluded that the field reduces the aggregative stability of the magnetic oil.
