Abstract

Registration of geomagnetic field variations with a magnetic modulating sensor. O.L. SOKOL-KUTYLOVSKII, D.S. TYAGUNOV (Institute of Geophysics, UrB RAS, Yekaterinburg).

The possibility of using magnetic modulating sensors of the weak magnetic field with amorphous ferromagnetic core operating in the mode of autoparametric signal gain of magnetic induction to measure the amplitude and phase variations of the geomagnetic field in the frequency range 0.01–30 Hz. Resolution of magnetomodulation sensors with autoparametric signal increase of magnetic induction in ferromagnetic amorphous core with offset longitudinal magnetostriction is not more than 1 pTl. Examples of  synchronous recording of the amplitude of the three components of the variations of the geomagnetic field in different parts of the measured frequency range, recorded during a weak magnetic storm intensity of five points are given. Information obtained by magnetomodulation sensor about the amplitude and phase of geomagnetic variations, together with data on the amplitude of the electric field of electromagnetic waves can be applied in geophysics to the different methods of magnetotelluric sounding.
