Abstract (en)
The ignition coil (1) comprises a magnetic circuit (7, 8), two windings, primary (2) and secondary (3), arranged coaxially around a core (7) of the magnetic circuit (7, 8). According to the invention, the magnetic circuit (7, 8) consists of grains of magnetisable material which are oriented by powering at least one of the windings (2 or 3) prior to an operation of impregnating a resin (60) polymerising the whole, said grains being arranged within a space defined by the casings (4) and (6). <IMAGE>
