A comparative analysis of the parameters of the components of the magnetic field and electrical potentials at the polygon of the IKFIA of the SB RAS near Yakutsk, far from industrial interference from the autumn of 2016 to the winter of 2018, is given. Seasonal variations of electric potentials are presented from 17.10.2017 to 07.02.2018. The variations of the Earth's magnetic field and electrical potentials during a large magnetic storm are compared on 07-09.09.2017. The correlation coefficient obtained is 0.5-0.9.
The measurements of electric currents flowing through pipelines buried in permafrost during lightning discharge terminating to ground near pipelines in Yakutia are presented. In addition, there are measurement results of telluric current flowing through pipelines during geomagnetic storms. The influence of a direct current flowing through the metallic pipe on the “pipe-ground” potential variation in the piece of pipeline with length of 150 m and diameter of 110 mm.
