摘要
由地球磁场的基本特征和电磁场理论,证明了流体外核不可能产生偶极磁场,地磁发电机理论对偶极磁场是无效的.并对地球和天体磁场的研究方向和方法进行了展望:偶极场与核心部分的自组织结构有关,多极子场与外部各层的组织结构或运动状态有关.
From the basic characteristics of the Earth＇s magnetic field and electromagnetic field theory, it is proved that the fluid outer core can not produce a dipole magnetic field. To a dipole magnetic field, geomagnetic dynamo theory is invalid. It makes the prospect of the research and methods of the earth and magnetic field of the celestial bodies, and suggests dipole field is related with the self-organization of the core, and the multi-pole field has the connection with the external layers of the organizational structure or with the state of the motion.
