Abstract
The influence of the Arctic oscillation phenomenon on the generation of the Earth’s magnetic field is considered. The corresponding mathematical model describing the dynamics of a thin layer of an electrically conductive incompressible fluid is built in a rotating coordinate system, and the movement of ice covers is modeled as a oscillation of a flat infinite wall. The constructed model is analyzed in order to study the features of the generated magnetic field. As a result, functional dependences for the hydromagnetic parameters of the oceanic arctic medium are analytically presented, which describe the dynamics of hydromagnetic processes during the movement of ice covers, which make it possible to reveal the existence of two different types of oscillatory motions of a continuous medium and a magnetic field, and to indicate graphical interpretations of the dependences of the magnetic induction components with distance from the source of disturbances.
