Zusammenfassung:	A transverse flux induction heating apparatus (1, 100), defining a first longitudinal axis (X, R), for heating a metallic strip (11), the apparatus comprises at least two induction coils (2, 4; 102, 104) arranged on respective planes parallel to each other and parallel to said first longitudinal axis, and mutually arranged at a distance such to allow the passage of the strip between said at least two induction coils along a second longitudinal axis (Y, S) perpendicular to said first longitudinal axis; at least two compensation poles (20, 22, 24, 26; 120, 124), each compensation pole being constrained to a respective induction coil; wherein each compensation pole comprises a winding (28, 128), having at least one turn (29, 129), and a first auxiliary magnetic flux concentrator (30, 130) surrounded by the at least one turn; wherein at least one of said at least two compensator poles is adapted to move along the first longitudinal axis.
