Abstract

A magnetic yoke having a yoke core that has a magnet, on which a first yoke arm and a second yoke arm are developed in such a way that the magnet and the two yoke arms open up a yoke opening, and having a first pair of pole pieces, which extend into the yoke opening and are positioned at a distance to each other in a first direction in such a way that a first gap is developed between the first pair of pole pieces and having a second pair of pole pieces, which extend into the yoke opening and are positioned in a second direction, that is aligned perpendicular to the first direction, at a distance from each other in such a way that a second gap is developed between the second pair of pole pieces. A micromechanical component having such a magnetic yoke is also described. A method for producing a magnetic yoke and a micromechanical component is also described.
