摘　　要：基于磁力线定义和均匀磁化球体周围的磁场分布,通过解算微分方程,推导出一个简单的磁力线簇公式,便于在地磁场研究中绘制均匀磁化球体的磁力线。On the basis of the definition of the magnetic field line and the distribution of magnetic field around an uniform magnetized sphere, the article resolves a differential equation and deduces a simple expression of the magnetic field lines,which makes it easy to draw the magnetic lines for an uniform magnetized sphere in geomagnetic research.

关 键 词：地磁场 均匀磁化球体 磁偶极子 磁力线
