这种变化与地球磁场曾经发生过的变化相比还算温和的——有时地球磁场会完全翻转，地磁北极和地磁南极会对调。

These changes are mild compared to what Earth's magnetic field has done in the past —sometimes the field completely flips, with the north and the south poles swapping places.

处于亮椭圆地区的北极极光与南极极光相比，显得体积较小但密度更大。 这意味着土星的磁场并不是均匀分布的。

This implies that Saturn's magnetic field is not equally distributed across the planet.
