This inductor system is the instrument of external straightening of dents in the metal coating of car body. The use of low-frequency plane-parallel magnetic field instead of a high-frequency magnetic field to create conditions for the transformation of the natural repulsion to attraction of sheet conductor is suggested. The low-frequency field is generated by inductor system by dint of flat circular turn. The plane-parallel magnetic field is generated by a rectangular turn. The low-frequency field penetrates the sheet workpiece in the construct. The theory and experiment indicate that plane-parallel magnetic field doesn’t diffuse almost. Conclusion calculated ratios to analyze the processes of magnetic pulse attraction in the system based on the solution of Maxwell’s equations for non-zero intensity components of the electromagnetic field. The Maxwell’s equations are transformed by Laplace zero initial conditions. In this case the integral sinus-transformation Fourier are applied. The problem is solved in the plane-wave approximation. Valid for plane waves directly proportional relationship between the tangent vector components of the electromagnetic field on the surface of conductor. For the analysis of processes in combined inductor system for a magnetic-pulsed «pulling» a predetermined part of the metal sheet were obtained the population of calculated expressions. The magnetic pressure on the metal sheet is caused by force action on the part of the excited fields. It is determined solely amplitude of penetrate field and is directed towards the working surface of the inductor. Finally, there is a predetermined part of the attraction of the sheet metal. The operating frequency of the plane-parallel field can be quite small. This choice doesn’t influence the diffusion processes in the system, but allows for the most efficient mode of implementation of a given production operation.</em> </strong>}, number={3}, journal={Electrical Engineering & Electromechanics}, author={Voloncevich, D.
