Figure 4

Typical daily (May 20, 2018) fluctuation of geomagnetic field induction in the southern Baltic Sea measured at Hel Geomagnetic Observatory (φ = 54°36.5'N, λ = 18°49.0'E), the Institute of Geophysics of the Polish Academy of Sciences (GOH, 2018)

Figure 5

Two spatial configurations of combined natural and artificial magnetic fields in the vicinity of a power (cable Bc1, Bc2 – induction from the core of the cable; Bg– geomagnetic induction; B1, B2 – resultant induction)

Figure 6

Example of modification of geomagnetic field declination in the vicinity of SwePol Link HVDC (calculated for the real data: power – 600 MW, voltage – 450 kV, distance between cables – 5 m, cable orientation – north–south)
