This video shows 2 spectra of signals recorded on a PC. The signal is taken from the inductive sensors presented at the beginning and end of the video. But the left sensor is connected to ground. Interesting signals at frequencies of 1-3 Hz, their changeable shape differs markedly from straight lines of 50 Hz and overlying harmonics. As well as other signals ~10, ~15, ~25, ~35 Hz and variable activity at fractions of a hertz. It is known from open sources that the range from 30 to 300 Hz is used for communication with strategic submarines. And the range is from 3 to 30 Hz for communication with underground objects and experimental studies. More frequencies up to 10 Hz belong to the geomagnetic background of the Earth...
