Abstract
The invention relates to a magnetic field measurement device, including a detector () configured to measure the amplitude of an output signal at a harmonic of an oscillation frequency of an excitation source, said amplitude being proportional to the magnetic field (B) to be measured, characterised in that it comprises an excitation circuit configured to associate with a principal excitation source (Bcosωt) oscillating at a principal oscillation frequency at least one secondary excitation source (Bcos(ω/3t+Φ)) oscillating at a secondary oscillation frequency that is a fraction of the principal oscillation frequency, said fraction being odd if said harmonic is odd, and even if said harmonic is even.
