About the nature of the dipole magnetic-field of planets
Abstract
A hypothesis of a model of the origin and maintenance of the magnetic-field of the Earth is suggested. Three independent and simultaneously acting factors of different physical nature are taken as the basis of the model: the Coriolis acceleration due to the Earth's daily rotation, electrical conductivity of the liquid layer of inner part of the Earth, and the radial gradient of temperature. A possible mechanism of the Earth’s magnetic field repolarization and its correlation with the thermal conditions in the inner part of the Earth are shown.
