The invention relates to a magnetic inductor for heating parts by means of induction, having a geometry with a density greater than or equal to 99.9% (absence of pores), produced by a plurality of welded layers formed by metal dust particles of a conductive, non-magnetic material (such as, inter alia, copper, tin, aluminium, gold, or silver), preferably copper or a copper-based alloy, having a spherical shape and a grain size between 40 and 100 µm, and in a single-piece part including electrical and mechanical connection means. The invention also relates to a method for producing the magnetic inductor with EBM technology (electron beam melting/production technology based on electron beam fusion), using a system comprising an electron gun, a vacuum chamber, a working chamber and a manipulation system.
