The technique for analytical determination of ferromagnetic conductor skin layer characteristics in a sinusoidal electromagnetic field under conditions of the conductor heating and non-linear magnetic properties has been developed. The proposed approach can be used for induction-heating installation engineering design. According to this, a conductor non-linear magnetization curve is firstly replaced by one and then by two linear sections. It is defined that conductor skin layer has constant values of specific conductivity and average temperature. Electrodynamics linear equations are solved for conductive semispace. Such skin layer parameters as an estimated magnetic permeability, a skin layer thickness and its average temperature, time of electromagnetic influence on the conductor at given maximum conductor surface temperature, electromagnetic field pressure on the conductor, resistance and inductance of the conductor are calculated. Reliability of the technique is confirmed by concordance of ferromagnetic conductor resistance and inductance with values obtained from other techniques.

The study is devoted to dynamics of the rotationally reciprocating stirred tank with four-bar linkage actuator. The dynamic model is constructed by reduction of link masses and moments of inertia, as well as moments of driving forces and resistance forces to the reduction link, which is a crank. It is shown that the angular velocity of the crank is not constant, so a flywheel is installed to provide the required rotation regularity. The resulting mathematical model can be used in construction and design of the stirred tanks.

In this article, we present a hypothesis about the nature of anti-adhesion as a method of processing cutting and deforming tools by the magnetic field. This hypothesis is based on analysis of operating experience and experimental studies on a wide range of instruments. We propose to study the influence of magnetic fields on the adhesion process using an atomic-electron approach based on examination of the processes taking place at the level of the crystal lattice of the nanostructure's magnetized body. Theoretical modeling shows that the influence of the magnetic field on the process of adhesion may be due to a change in the energy state of nanostructures in the crystal lattice in accordance with the quantum-mechanical nature of their response to magnetic effects. Specific attention is paid to the methodological aspects of experimental modeling. New results were reached that illuminate the effect of wear on the prevailing conditions of adhesive wear on the magnetization instruments. A new mechanism of influence is proposed by processing the magnetic field on the wear, from which it is concluded that the appearance of an electron system with a modified energy level that is resistant to the formation of strong chemical bonds caused the adhesion.
