1、an imaginary line passing through both magnetic poles of the Earth.

2、The magnetic poles swap every 300, 000 years, a process that normally takes up to 5000 years.
磁極互換每30萬年發(fā)生一次，每次需要近5000年的時間完成這個過程。 1995年在俄勒岡發(fā)現(xiàn)了古代巖漿不尋常的磁場狀態(tài)。

3、Plait goes on to note that, for the record, the Earth’s magnetic poles are distinct from its axis.
普萊特還講到根據(jù)記錄地球的磁極與他的軸線之間有一段距離。

4、So this is one of the magnetic poles and this is the other magnetic pole.
這是另一個磁極，一個磁極和。

5、Plait goes on to note that, for the record, the Earth's magnetic poles are distinct from its axis.
普萊特還講到根據(jù)記錄地球的磁極與他的軸線之間有一段距離。

6、The movement of the magnetic poles is unrelated to the location of the North pole, for example.
比如，磁極的移動與北極的地點無關。

7、The story does have some facts in it, however. For example, the magnetic poles are indeed moving.
但是故事本身存在一些事實依據(jù)。例如，磁極確實在移動。

8、For example, the magnetic poles are indeed moving.
例如，磁極確實在移動。
