Abstract
In this paper we analyze the following methods for extending the frequ ency range of fluxgate magnetometers: suitable design of the electroni cs, increase of the excitation frequency, and the use of various core materials (permalloy, amorphous alloys). These methods were applied to magnetometers which measure, by automatic compensation, the field in the proposed frequency range. The magnetic field range of 0-100 mu T a nd the frequency range of 0-3000 Hz can be measured using the same flu xgate sensor.
