Abstract

A fluxgate magnetometer is described that is based on the magnetization reversal excitation of disc-shaped magnetic core by rotating magnetic field with magnitude enough to saturate it. The target field components are registered by means of the second harmonic of the current response signal. The model of response signal is developed and a sensor prototype was built and experimentally tested. The measured sensitivity dependences upon the excitation field amplitude at different frequencies coincide well with predictions of the model.
