Comparative Analysis of Jupiter Magnetic Field and Magnetic Field Model

Abstract

Jupiter has the strongest magnetic field among the planet in the Solar system. In this paper,Jovian magnetic field and its'models including VIP4, VIT4, O6 and V1 was investigated. And then the calculated magnetic field results by these models were compared. It was found the range of magnetic filed strength by these four models were consistent. While global magnetic field distribution were not exactly the same,especially the position of magnetic south poles. The deviation were small between the models and magnetic data obtained from spacecraft missions. It can provide necessary theoretical basis and computational model support for environmental protection of Jupiter exploration. VIP4,VIT4,O6 and V1 was investigated.
