Abstract
A method for operating an ignition device for an internal combustion engine, in which via a rotating magnetic pole wheel a voltage signal with a number of positive and negative half-waves is produced in at least one coil arrangement that is located on a core leg of an iron core during each rotation of the magnetic pole wheel, wherein the voltage signal is used to determine the gap width of the air gap between the magnetic pole wheel and the core leg.
