Device for measuring a magnetic field with Laplace force, this device comprising: - a substrate extending essentially in a plane called "plane of the substrate", - a first rigid frame (10; 222) extending essentially in a plane called "plane of the first frame" and suspended above the substrate, this first frame being able to be displaced relative to the substrate in rotation about a first axis of rotation parallel to the plane of the substrate, and the first rigid frame comprising a through central void, - an electrical conductor fixed with no degree of freedom onto the first rigid frame and comprising a first and a second ends, this conductor being wound, between its first and its second ends, around a winding axis at right angles to the plane of the first frame, - at least one first hinge mechanically connecting the first rigid frame to the substrate, this hinge comprising a first electrical track electrically connecting the first end of the electrical conductor and a first contact pad (42; 192) secured to the substrate, - a second hinge (39; 248) mechanically connected to the first rigid frame and comprising a second electrical track electrically connecting the second end of the electrical conductor to a second contact pad secured to the substrate, and - at least one first sensor (60, 62; 152, 154) capable of measuring a physical quantity representative of the amplitude of the angular displacement of the first rigid frame about its axis of rotation, characterized in that: - the first hinge and its first track are situated inside the central void of the first rigid frame, and - the second hinge (39; 248) and its second track are situated outside the central void of the first rigid frame. - a substrate extending essentially in a plane called "plane of the substrate", - a first rigid frame (10; 222) extending essentially in a plane called "plane of the first frame" and suspended above the substrate, this first frame being able to be displaced relative to the substrate in rotation about a first axis of rotation parallel to the plane of the substrate, and the first rigid frame comprising a through central void, - an electrical conductor fixed with no degree of freedom onto the first rigid frame and comprising a first and a second ends, this conductor being wound, between its first and its second ends, around a winding axis at right angles to the plane of the first frame, - at least one first hinge mechanically connecting the first rigid frame to the substrate, this hinge comprising a first electrical track electrically connecting the first end of the electrical conductor and a first contact pad (42; 192) secured to the substrate, - a second hinge (39; 248) mechanically connected to the first rigid frame and comprising a second electrical track electrically connecting the second end of the electrical conductor to a second contact pad secured to the substrate, and - at least one first sensor (60, 62; 152, 154) capable of measuring a physical quantity representative of the amplitude of the angular displacement of the first rigid frame about its axis of rotation, - the first hinge and its first track are situated inside the central void of the first rigid frame, and - the second hinge (39; 248) and its second track are situated outside the central void of the first rigid frame.
