Claim 5:
6. An electromagnetic actuator comprising:
an armature;
a magnetic coil configured to generate a magnetic field by which the armature is movable in an axial direction in an armature space;
an operating element motion-coupled to the armature; and
a flux-directing part that:
is disposed at an axial end of the magnetic coil;
is embodied in two parts, the two parts including:
a top part facing away from the armature and embodying a first bearing point; and
a base part facing toward the armature and embodying a second bearing point; and

has a recess constituted by a first bore extending in the axial direction in the top part and by a second bore that is adjacent to the first bore and that extends in the axial direction in the base part;

wherein:
the operating element is axially displaceable within the recess and the first and second bearing points; and
the electromagnetic actuator includes at least one of the following two features (a)-(b):
(a) the first bore has, in an axial region of extent of the first bearing point, a first inside diameter that is smaller than an inside diameter of the first bore in an axial region at which the first bearing point does not extend; and
(b) the second bore has, in an axial region of extent of the second bearing point, a second inside diameter that is smaller than the inside diameter of the second bore in an axial region at which the second bearing point does not extend.
