Abstract
The work is an attempt to find the force with which an electromagnetic system with Foucault currents acts on itself. It is taken into account that the average force with which the source of the alternating magnetic field and the inductive Foucault current is equal to zero, the self-force arises as a result of the interaction of unclosed Foucault conduction currents with the displacement current created by a conductor located in a non-uniform magnetic field. The average force acting on a symmetrical conductor located between the poles of an electromagnet turned out to be different from zero. The greatest value of this force is observed in the region of maximum inhomogeneity of the magnetic field.

The Foucault current density is proportional to the frequency of magnetic field oscillations
Summary
In a massive conductor located in an alternating magnetic field, the so-called Foucault currents arise [1]. The conservation of momentum is ensured by the force FA, formally speaking, acting on the displacement current [7] [8] Since this force is determined by the square of the current strength, the force averaged over the period of change of the external magnetic field is not equal to zero. Without considering the Foucault displacement currents, the theoretical analysis of dynamic processes in conductors located in a non-uniform alternating magnetic field is practically impossible. The extremely large value of the current strength is the main feature of the Foucault currents This means a real possibility of developing a propulsion device that uses an electromagnetic field to create a reactive force. In a certain sense, this method of creating an electromagnetic reactive force may turn out to be more promising than EM-drive [13], which requires very high frequencies of an alternating electric field
