STUDY OF DESIGN CONSIDERATIONS OF FLUXGATE SENSING ELEMENT FOR MAGNETIC FIELD MEASUREMENT

Abstract

This thesis’ aim is proposing comprehensive simulations to model fluxgate magnetic core’s behavior to explain how current and magnetic distribution inside the core depends on both excitation parameters, and core’s magnetic properties. Furthermore, two core’s design configurations were considered, to be investigated, corresponding to different excitation mechanisms. For each design configuration, detailed finite element analysis is presented to study the influence of frequency, core dimension, and excitation mechanism on current and magnetic distribution inside the sensor’s core. Results presented in the thesis provide performance map for tracking the fluxgate core behavior under various operational
