| 摘 要： | 以电磁学中的假想磁荷理论为基础，建立了内外同轴的两环形永久磁铁相互作用力的力学模型，并在此基础上，推证出了两环形磁铁磁作用力的数学模型，从而在不做任何假设及简化的条件下，建立了内外同轴的两环形磁体承载力的计算公式．应用该计算公式能够使两环形磁体相互作用的各机械量具有很高的计算精度．该公式的推证建立方法对分析和建立其它形式的磁体相互作用力的计算公式具有普遍意义．因此，计算磁体磁作用力的等效磁行法是研究永久磁体承载力的一个新的有效途径．

| Abstract: | Based on the theory of equivalent magnetic charge, the mechanical and mathematical model of magnetic force of coaxial permanent magnet rings is built. Then, the formula for load force of both the permanent magnet rings is established without any hypothesis and simplification. The mathematical result of the mechanical parameters is very accurate when the formula is used for both permanent magnet rings. This method may be applied to calculate tbe magnetic force of other type of permanent magnet and is a new way to study load force of permanet magnets. |
