1. A magnetic field detector comprising:

  • an electrical coil;

    a resilient member, separate from said coil, on which said coil is mounted, said resilient member being bent to form two shanks which are interconnected by a bend at one end of said resilient member, each shank having a free end, and said coil being mounted at the free end of one of the shanks, and means for rigidly fixing said resilient member at a region of the free end of the other shank for causing said resilient member to vibrate as a whole upon displacement of said coil;

    means for feeding said coil with a controllable electrical current; and

    means for detecting movement of said resilient member caused by displacement of said coil in the presence of a magnetic field, when said coil is fed with said electrical current, as a measure of said magnetic field.
