- Аннотация: This paper is a study of a possible mechanism of magnetic field amplificationi n the thin transition layer just outsidet he magnetopauseo f a quickly spinningp lanet. Here we presenta nalysiso f a new magnetosphericm agneticf ield source arising due to the rapid rotation. When the ionosphere and magnetopause conductivitieso f the rapidly rotatingp lanet are sufficientlyh igh (but lesst han the field-alignedc onductivity)t he circulatione xistsa t the magnetopausine the open field line bundles. The toroidal magnetic field is generated there from the poloidal ambient magnetosheath magnetic field by differential rotation. The requirement of the a effect existence is satisfied due to the deviation from axial symmetry about the planer's rotation axis of the initial magnetosheath velocity and magnetic fields. The increasing poloidal magnetic field can be regenerated from the toroidal one by the a effect. This mechanism may act as a hydromagnetic dynamo. The generated magnetic field penetrates into the magnetospherea nd adds to the magnetospheric magnetic field.
