摘要
地球自转变慢的事实,使刚性内核和地幔处于不同频幅的扭摆振荡状态.由地球温度分布和汤姆逊效应,知道地核带正电,地幔带负电.所以外核正电荷的振荡是形成基本场的原因.由此对地磁倒向规律作出物理说明.
Because of slowing of the earth rotation, the earth's core and mantle are twists and oscillates with different frequency and different amplitude. As a deduction of the temperature distribution and Thomson effect of the earth that the core is of electropositive and the mantle is of electronegative. The oscillation of positive charge in outer core is causative of the general field. A physical description of the geoeagnetic reversal is given.
