摘要：
Fluxgate sensor is a kind of magnetic sensor which is used in low magnetic field measurement. The key components are magnetic core and exciting current. Easy saturation magnetic core is required and square-wave current excitation is fed to exciting coil in order to make magnetic core operated at saturation region. In this paper, three kinds of ferrite core that had an operating frequency of 2-20 kHz were used in the experiment. Various kind of exciting current was fed to exciting coil and magnetic field detection capability was studied. Resulting of magnetic field measurement in range of 0-600 mu T which were obtained from the proposed sensor was show in experiment.
