Abstract

An electromagnetic actuating apparatus having an armature unit, which can be moved through a movement distance in an axial direction relative to a stationary core unit and in reaction to an operating current being passed through a coil unit, which armature unit magnetically interacts axially at one end with the core unit over a control range which at least partially overlaps axially along the movement distance, which, as a section of the armature unit, has a first profile section and, as a section of the core unit, has a second profile section, with an air gap formed between them and forms an extent at right angles to the axial direction.
