中文名；地球磁场

外文名；The Earth magnetic field

概述；场言是偶极型的

简介；不是孤立的，它受外界扰动的影响

形成原因；关于地球磁场成因的

磁极位置；磁北极,磁南极

'''地球磁场'''（the earth magnetic field）是指地球[[周围]]空间分布的磁场。

偶极型，近似于把一个磁铁棒放到[[地球]]中心，磁北极（N）极处于地理南极附近，磁南极（S）极处于地理北极附近。磁极与地理极不完全重合，存在磁偏角。

地球磁场属于电磁场，是通过外核的电子随地球自转的电流效应（近似于电生磁）产生的磁场。<ref>[https://wenku.so.com/d/104983abc604db971e314d6e3597ba78 地球磁场],360文库 , 2021年4月10日</ref>
