Abstract: The paper investigates the numerical calculation of the electrical coils belonging to the inductive transducers with magnetic fluids for inclinations and aerodynamic measurements. One way to improve the construction of these transducers is to increase the electrical frequency for their coils. In this case, the thickness of the coils can be reduced by a large amount. The paper presents a numerical model for calculating the inductance of these ultra thin coils versus the level of the magnetic fluid core, the geometrical dimensions, and the magnetic properties of materials.
