An electromagnetic actuator and a method for controlling the actuator comprising at least one armature () and two coils (). The voltage gradient at the two coils () is measured during a sudden increase in voltage. From this measured data, a subtractor () computes a third voltage gradient () from which a logic unit () determines the position of the armature () without the use of an additional sensor.
