Abstract

A magnetic actuator includes: a plate having a main plane of extent and mounted rotatably about at least one first axis of rotation which is parallel to the main plane of extent, the plate having at least one conductor loop parallel to the main plane of extent; a magnetic bracket situated beneath the plate and having a U-shaped magnetic flux conducting rail and a hard magnet whose magnetization is perpendicular to the U-shaped opening, the magnetic bracket and the plate being aligned with one another in such a way that the opening in the magnetic bracket points toward the main plane of extent of the plate, the U-shaped magnetic flux conducting rail having a main direction of extent parallel to the first axis of rotation, and the plate being deflectable about the at least one axis of rotation by energizing the at least one conductor loop.
