This magnetic field sensor comprises: - a generator generating N magnetic fields CMi by means of at least one permanent magnet (AlphaRhoi), each field CMi having an intensity Ii in the direction of measurement, each transducer TMi being positioned inside the field CMi forming a measurement block (Bi) for which the range wherein the resistance of the transducer TMi of this block varies linearly within ±xi% is offset by Ii and becomes [ai + Ii; bi + Ii], each intensity Ii being different from the others, - a calculator (22) capable: . of selecting the suitable measurement block for which the intensity of the magnetic field to be measured is included in the range [ai + li; bi + Ii] of said block, and . of establishing the measurement of the intensity of the magnetic field on the basis of the measurement of only the selected measurement block. |
