Modelling the Fluxgate Sensors with Magnetic Field Concentrators

Abstract

This paper presents the efficiency analysis of magnetic flux concentrator attached to the core of fluxgate sensor made of amorphous alloy ribbon. Simulations were carried out using open-source software toolchain covering Netgen, Elmer FEM, and ParaView. The results indicate that the increase of the length of the core significantly reduces the demagnetization factor, which increases the sensitivity of fluxgate sensor. However, the use of magnetic flux concentrator does not lead to significant increase of sensitivity of fluxgate sensor with core made of thin layer magnetic material.
