摘要
关于地磁场的起源,至今仍是一个没有得到解决的问题。相关的解释很多,如:永磁体假说,电荷旋转假说,热压电效应解释,温差电效应解释,自激发电机假说等,但由于都存在着一些自身无法解决的问题而未能被广泛接受。地球周围有一个被称为范爱伦带的带电粒子连续分布。是范爱伦带产生了地磁场,还是地磁场产生了范爱伦带?经过考察,可能是后者。但是,地磁场的起源问题仍然不能由此得到解决,仍是一个未解之谜。
The origin of geomagnetic field remains to be answered. There are many explanations such as permanent magnet hypothesis, thermal -piezoelectricity effect hypothesis, thermoelectric hypothesis, and selt- excited dymano hypothesis etc, but all get no general acceptance for certain problems which exist in themselves and can not be settled. A succession of charged particles have been gathering around the earth, which is called Van Allen belts. Does Van Allen belts generate or come from the geomagnetic field？ According to research, the latter has a strong possibil- ity to be the cause, which, however, does not equal to discovering the origin of the geomagnetic field ; namely, its origin is still a riddle.
