Moreover, Gilbert was the first to systematically study phenomena caused by the earth's magnetism; he was the one who proved that the compass needle always points to the magnetic north pole of the earth.

威廉吉尔伯特（ 5月24日1544至30年1603年11月）是伊丽莎白一世的王室医生。此外，吉尔伯特是第一个系统研究的现象所造成的地球磁场，他是一个谁证明，磁针总是指向磁北极的地球。

The earth has a magnetic north pole and a magnetic south pole. These poles are close to, but not exactly at, the earth's axis of rotation . What's more, they are constantly moving!
