Abstract
We analyze the possibility of measuring of weak low-frequency alternating magnetic fields against the background of geomagnetic variations and estimate the lower limits of detection of weak periodic and aperiodic signals of magnetic induction in the geomagnetic field by magnetomodulation sensors. It is shown that the components of magnetic induction of continuous geomagnetic noise measured in a narrow frequency band by two magnetomodulation sensors located at a distance greater than one meter are random and independent.
