Coil comprising a closed magnetic circuit (1) consisting of cut out and piled metal sheets so as to form a first U-shaped part (12), of which one of the portions (12a) is cut to form a chamfer (12b), a second L-shaped part (13) comprising a portion (13a) cut to form a chamfer (13b) so that, after setting in place, on the branch (8), an insulating casing (6) containing primary (4) and secondary (5) windings and inserting a permanent magnetic (2) between the chamfers (12b and 13b), the first and second parts (12 and 13) are integral with each other, through rivets (14, 15) and prolongations (9b) of the metal sheets (9) forming a shunt circuit of the magnetic flux created by the primary winding (4). |
