На основе результатов инструментальных наблюдений, выполненных в магнитных обсерваториях ‒ Геофизической обсерватории «Михнево» ИДГ РАН и ряде обсерваторий международной сети INTERMAGNET, расположенных на удалении от главных магнитных аномалий Земли, и данных IERS о неравномерности вращения Земли показано, что в рассмотренных случаях индукция геомагнитного поля увеличивается с ростом скорости вращения Земли и, наоборот, уменьшается при ее падении. Получена количественная зависимость между абсолютной величиной вектора индукции геомагнитного поля и величиной LOD, равной разнице между наблюдаемой и эфемеридной длительностью суток. </p></abstract><trans-abstract xml:lang="en"><p>We consider the joint variations of the magnetic field and the Earth’s rotation speed. It is shown that in the considered cases, the induction of the geomagnetic field increases with increasing speed of rotation of the Earth and vice versa decreases with its fall. We used the results of instrumental observations performed at magnetic observatories ‒ the Mikhnevo Geophysical Observatory of Sadovsky Institute of Geosphere Dynamics of Russian Academy of Sciences and a number of observatories of the international INTERMAGNET network ‒ located at a distance from the main magnetic anomalies of the Earth, and IERS data on the unevenness of the Earth’s rotation. A quantitative relationship has been obtained between the absolute magnitude of the geomagnetic field induction vector and the LOD value equal to the difference between the observed and ephemeris day duration. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>геомагнитное поле</kwd><kwd>скорость вращения Земли</kwd><kwd>длительность суток</kwd><kwd>вариация</kwd><kwd>корреляционные связи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>geomagnetic field</kwd><kwd>Earth’s rotation speed</kwd><kwd>day duration</kwd><kwd>variation</kwd><kwd>correlations</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследования выполнены в рамках государственного задания Министерства науки и высшего образования РФ (тема № 125012700798-8).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
