This paper presents a complete set of SIMULINK models, which allow exhaustive behavioral simulations fluxgate system to be performed. The model construction is detailed and it applied the Vacquier-type sensor. Well known characteristics these sensors are confirmed through simulations. In spite this simplicity, has been successfully used describe variation output sensor with amplitude frequency driving current. Using previously developed 2nd harmonic magnetometer, some preliminary experimental results obtained confirming appearance at its output.
