An electromagnetic camshaft-adjuster device having an armature unit () drivable along an axial direction in reaction of a current feed of a stationary inductor unit (), which for interacting with an adjusting unit () causing adjustment of a camshaft of an internal combustion engine is configured with a slide and/or tappet unit, wherein on and/or in the armature unit and/or the adjusting unit, a permanent magnet element () is provided and the inductor unit and the armature unit are at least partially received in a housing or supporting unit, and wherein the supporting unit is associated with a configured stationary magnetic field detection element () preferably for contactless magnetic interaction with the permanent magnet element, which is configured so that in a current feed condition and a non current feed condition the inductor unit an axial position of the armature unit and/or the adjusting unit can be determined electronically by evaluating a magnetic field detection signal of the magnetic field detection element.
