The invention relates to a method for determining a position of a movable armature (103) of an electromagnetic actuator (101), wherein the armature by means of energization of a coil (102) of the electromagnetic actuator (101) is movable, wherein a semiconductor switch (M1), a current sense resistor circuit (RS) and the coil (102) are connected in series, wherein the position (x) of the armature (103) is determined taking into account a frequency of a vibrating signal in a vibratory electrical system, wherein the coil (102) as a frequency-influencing element of the oscillatory electrical system is used, wherein a potential at a node between the coil (102) and the current sense resistor circuit (RS) is controlled by means of the semiconductor switch (M1) to a desired value.
