Claim Text:
1. A device for measuring magnetic fields with Laplace force, this device comprising: a substrate extending essentially in a plane called the “plane of the substrate”, a first rigid frame extending essentially in a plane called the “plane of the first frame” and suspended above the substrate, the first frame being moveable relative to the substrate in rotation about a first rotation axis parallel to the plane of the substrate, and the first rigid frame comprising a central through-recess, a fixed electrical conductor fixed, with no degree of freedom, to the first rigid frame, the fixed electrical conductor being wound about a winding axis perpendicular to the plane of the first frame, at least one first hinge mechanically connecting the first rigid frame to the substrate, the at least one first hinge comprising a first electrical track electrically connecting a first end of the fixed electrical conductor and a first connection pad fixedly attached to the substrate, a second hinge mechanically connected to the first rigid frame and comprising a second electrical track electrically connecting a second end of the fixed electrical conductor to a second connection pad fixedly attached to the substrate, and at least one first sensor capable of measuring a physical quantity representing the amplitude of the angular displacement of the first rigid frame about said first rotation axis, wherein:
