The purpose of this theoretical investigation is the modeling of finish-strengthening under conditions of a rotating field for the definition of ferromagnetic indenter kinematic properties. This method is based on functioning devices offered by D.D. Logvinenko. The basis of these devices is an inductor located into the case. This inductor represents a modified stator of an induction motor. In the stator bore there is installed a cylindrical pipe made of nonmagnetic material the inner surface of which limits a working area of the device. From the obtained results of theoretical researches it follows that the kinematic properties of ferromagnetic indenters are defined by field parameters – induction of a direct and an alternating fields, frequency and gradient of induction of an alternating field, and also magnetic and inertial properties of indenters.

The rotating electromagnetic field devices are presented and the physical effects that determine their application in hardening of the surface layer during processing by ferromagnetic indenters are disclosed. The results of experimental studies are presented that reveal the technological capabilities of magnetodynamic processing and the field of its practical application in the technology of manufacturing parts.
