Fluxgate magnetic field sensors are commonly used in the industry, navigation as well as in non-destructive testing. Moreover, recent development of such sensors is focused on effective application of thin layer magnetic cores, such as made of amorphous alloys. However, effective development of fluxgate sensors require method of modeling its core taking into account demagnetization. The paper presents the results of optimization of the shape of thin-layer core for fluxgate sensor. Due to the fact that possibility of application of finite elements method is limited in the case of thin layer, the method of moments was used. Considering the geometry of the core as well as magnetizing and sensing winding, the optimal proportion of the length/thickness parameter was determined from the point of view of sensor sensitivity. It was proven that value of this optimal proportion is strongly dependent of thickness of the core.
