Abstract
In the disclosed ignition apparatus for internal combustion engines provided with flywheel magnetos, the ignition spark interval is purely mechanically provided at the manufacturing stage. In the direction of rotation, the edges of both pole shoes and core legs which meet each other are sharply defined. The pole shoe, first in the direction of rotation, is formed so that it substantially coacts with the leg, second in the direction of rotation, when the leading edge of the second pole shoe comes into coaction with the front edge of the leg situated first.
