The analysis of electromagnetic processes occurring in the inductor system with a bifilar coil as well the numerical estimates of the characteristics of the excited currents under conditions of high intensity of penetration of the acting fields is conducted. In order to study electromagnetic processes in thin-walled windings of a bifilar, in contrast to their massive implementations, where there is an energy intense output into the surrounding space, a strict mathematical approach with application of the theory methods of electric-magnetic field is used. The numerical estimates are conducted with help of the obtained analytical dependences. It was shown that the amplitude of the current induced in the bifilar windings of the experimental model of the considered inductor system in the ratio to the exciting current does not exceed 10-15%, which is significantly less than the possible maximum of ~ 50%. It is noted that the radial distribution of the induced current, in contrast to the uniform distribution of the exciting current in the inductor, has an increasing character from the inner to the outer radius of the bifilar winding. The obtained results allow to assess the level of efficiency when choosing design solutions for the new elements of the equipment in the magnetic-pulsed metal processing. References 11, figures 3.

Key words: bifilar coil, flat circular inductor system, magnetic-pulse treatment of metals, energy transformation, solenoid-inductor.
