Paper Abstract

In this paper, the micro-fluxgate model of single core is presented. Under different excitation or external magnetic field conditions, the characteristics of the model were analyzed and then the structural parameters of the core were optimized by FEM. The simulation results show that: (1) the linear measurement range is 5.2e-7 to approximately 2.6e-4T; (2) the sensitivity is linear with the excitation frequency; (3) for Typel micro-fluxgate, a maximal sensitivity can be reached at 200KHz with the core width near to 0.7mm.
