Induction current contribution to the secular variation of geomagnetic field in accordance with the data of Ukrainian
geomagnetic observatories has been investigated. The dynamics of the monthly changes of the secular variations
depending on the values of the induction currents has been shown. Correlation between changes of secular variations and
solar activity has been found. Changes of solar activity outstrip secular variation changes.
Key words: magnetic field, geomagnetic observatory, induction current, secular variations, solar activity.
