DYNAMO MODELS CREATED ON THE PLANETS UNDER THE INFLUENCE OF TIDAL FORCES OF THE SATELLITE AND THE SUN

Vladimir Kochnev

Abstract

It is known that the movement of the liquid core creates electric currents, inducing a main magnetic field of the planet. The liquid core of the high temperature becomes ionized plasma (plasma), which It is quasi-neutral (not neutral) - by definition. One of the major geodynamo questions: what is the source of strength, causing fluid movement in the core of the planet? Many authors have investigated geodynamo: planetary rotation around its axis, the temperature difference and pressure as well as the Coriolis force. Moffatt (1980), at the end of his book, as expressed the problem mentioned above "... For example, it is not yet known that the ultimate source energy is the basic movements of the Earth's disk Dynamo". In this study, the role of the driving forces of the liquid core considered tidal forces created axial rotation of the planet and the influence of external objects (the Sun and planets, satellites). The value of the tidal force on the equator of the planet depends on the radius and the period of the axial rotation of the planet, mass, radius and the orbital period of the satellite around the planet. The paper presents the formula and the results of the calculation of tidal forces and forecast the relative values equatorial magnetic fields of the planets all the planets of the solar system. The interpretation of the results illustrated with drawings. The new version of the dynamo It helps to explain the reasons high intensity magnetic Jupiter's field compared to Saturn's fields, Uranus and Neptune, and much more Earth field intensity compared with fields of Venus, Mercury and Mars. The calculations of the correlation values the magnetic field at the equator: on the model according to the forecast and observations on the planets. Correlation coefficient is 0.997, that indicates a close relationship observed and estimates fields, and this is indirect evidence of the correctness of the adopted model.
