Abstract

A device for measuring magnetic fields with Laplace force, comprising a substrate extending in a substrate plane, a first rigid frame in a first plane moveable relative to the substrate about a first rotation axis parallel to the substrate plane with a central through-recess. There is a fixed electrical conductor wound an axis perpendicular to the plane of the first frame. There a first hinge connecting the first rigid frame to the substrate with a first electrical track. There is a second hinge connected to the first rigid frame with a second electrical track. There is a first sensor for measuring of the angular displacement of the first rigid frame. The first hinge and the first electrical track are inside the central recess of the first rigid frame and the second hinge and the second electrical track are outside the central recess of the first rigid frame.
