A method of pulsed magnetic attraction of thin sheet metals consists in their deformation by impact of the pulsed magnetic field of an induction multiturn rotary inductor system that is configured as a flat coil, above which a flat metal screen is placed. To implement the method of pulsed magnetic attraction an inductor is used, which is made in the form of three circular planar coils, two of which are placed on the top of additional screen, and the third one – from below. The coils of the inductor are connected so that the current therein flows in one direction, while the thickness of the additional screen remains unchanged along the entire cross-section and is selected from the ratio.
