摘要

我们用完全椭圆积分的形式给出了点磁体和环磁体之间静磁相互作用能的精确封闭表达式。能量的精确表达式显示出一个接近环形磁体对称轴的平衡点。我们的方法将对有关磁悬浮的研究和卡西米尔悬浮的研究有用。

Magnetostatic interaction energy between a point magnet and a ring magnet

We find an exact closed-form expression for the magnetostatic interaction energy between a point magnet and a ring magnet in terms of complete elliptic integrals. The exact expression for the energy exhibits an equilibrium point close to the axis of symmetry of the ring magnet. Our methodology will be useful in investigations concerning magnetic levitation, and in the study of Casimir levitation.
