ABSTRACT:
Disclosure is made of an inductor for working metals by the pressure of a pulsating magnetic field, wherein on the outer surface of a concentrator, which has a working opening to receive an article to be worked and a radial slot, there are provided annular grooves, the spacings between the annular grooves forming stiffening ribs of the concentrator; laid in said annular grooves are flat helical sections of a winding, the beginning of each section enveloping an electrically conducting rod arranged in a bore extending through the concentrator, being parallel with the axis of the working opening and being next to said annular grooves; the ends of each flat helical section are interconnected in parallel by means of a bus; in said concentrator ribs, there are provided threaded holes to receive screws whose butt ends press upon the electrically conducting rod.
