Summary:Current sensor comprising:one pair, of identical electrical coils with superparamagnetic cores and surrounded by a common shielding braid;a direct current excitation means configured to make a direct current flow in at least one of the coils of the pair of coils and a means of adjusting an intensity of the direct current;a first alternating current excitation means configured to make an alternating current flow at a first frequency in the coils of the pair that the direct current flows through;a second alternating current excitation means configured to make an alternating current flow at a second frequency greater than the first frequency in the two coils of the pair of coils;a means of measuring an electromotive force of the Néel Effect® type at the terminals of the two coils of the pair.
