The author considers the forces acting on a ferromagnetic particle from the side of the magnetic and thermal fields, as well as the forces opposing its penetration from the side of the surface layer of the polymer. The calculation of the forces acting on a ferromagnetic particle in the process of its introduction into the surface layer of the polymer is carried out using the example of nickel and polypropylene. The balance of forces required for the introduction of a ferromagnetic particle into the molten surface of a thermoplastic polymer and stable fixation in it is calculated. The universality of the approach used is shown for calculating the parameters of surface modification of thermoplastic products with different properties by ferromagnetic particles of different dispersion and characteristics.
