论文摘要
我们发现，在完全椭圆形积分方面，点磁体和环磁体之间的磁相互作用能的精确闭合表达。能量的精确表达式表现出一个平衡点，接近环磁体对称性的轴。我们的方法对有关磁悬浮的研究以及Casimir悬浮的研究将很有用。
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.
