1. Magnetic guiding device comprising:
a stator; and
a slide movable with respect to the stator along a guiding direction (Z), wherein the stator and the slide are magnetized or magnetizable such that a magnetic field extending through the stator and the slide will generate a magnetic supporting force (U) onto the slide acting along the guiding direction (Z), wherein the magnetic field extending through the stator and the slide will simultaneously generate a magnetic pretensioning force (F) which will urge the slide and the stator against each other.
