A new magnetometer using a ferrofluid fluxgate sensor for measuring the intensity of a dc magnetic field is presented. The electronic circuit with CMOS integrated circuits is described, as well as the ferrofluid fluxgate operation. The saturable fluxgate sensor uses orthogonal coupling between the excitation and pick-up coils
