二 | 世界地磁模型是所有现代导航系统的基础，包括海军导航系统和手机上的谷歌地图。最新的世界地磁模型，于2015年出版，相信到2020年可以使用。

三 | 但研究人员说，磁场变化如此之快，他们必须提前修改世界地磁模型。世界地磁模型原定于1月15日更新，但由于美国政府的关闭，时间不得不推迟到1月30日。地磁场在不断变化。

四 | 小科学普及：地磁极（来自维基百科）人类首先根据地球两极的方向来定义磁铁的南北极，而不是相反：磁铁的北极是指磁针自由旋转时转向地磁北极的末端。

五 | 由于两块磁铁的南北极相互吸引，这就意味着地磁场的北极实际上是地磁场的南极（即地磁场线指向地球中心的地方）。

六 | 南北磁极一般位于地极附近，但其位置随地质时间的变化而变化较大。

七 | 这种变化太慢，无法干扰罗盘的日常使用。

八 | 然而，平均每几十万年就会发生一次地磁反转，即南北极突然（与地质时间尺度相比）相互交换。
