Abstract
Based on the results of instrumental observations of geomagnetic variations at the Mikhnevo observatory of the IDG RAS and data from the IERS catalog, it was found that the frequency F of the main spheroidal mode of the Earth’s natural oscillations 0S2, distinguished in the spectra of magnetic field variations, changes with time, and the values of F are higher during periods of a decrease in the rotation speed Earth and below with its increase, An empirical relationship between the variations of F and the speed of the Earth’s rotation is obtained,
