Abstract
An electromagnetic induction apparatus for heating metal elements has at least one flat loop magnetic circuit open at its two facing ends, with an inductor wound onto the magnetic circuit. The inductor has two windings wound onto the magnetic circuit, respectively in the vicinity of the two ends of the loop, which windings are supplied by in-phase alternating currents. Each end of the flat loop is chamfered, the ends forming an air gap therebetween, in which the element to be heated is placed.
