Abstract
A device sensitive to a magnetic field (B) comprising a flap attached to a support by torsion hinges and a conductor. The conductor carries a current I and thus generates under the effect of a magnetic field a force which tends to cause the flap to turn about its hinge axis. The measurement of this rotation or of the compensation required to nullify the effect of the magnetic field (B) constitutes a measure of this magnetic field. Embodiments are disclosed having multi-turn conductors or ferromagnetic coatings instead of conductors on the flaps.
