摘要

本文建立了圆柱形永磁体与螺线管的等效模型。基于磁荷理论和库仑模型，推导了轴向磁力的表达式，得到了无量纲轴向磁力公式。通过进一步求导，得到了无量纲轴向刚度公式。深入分析了无量纲参数对轴向刚度的影响。无因次计算过程消除了因单位制差异造成的干扰，揭示了磁性刚度与磁体几何和材料性质之间的内在关系。这为电磁器件的优化设计提供了理论依据，在工程和科研领域都具有广泛的应用价值。

Dimensionless Analysis of Axial Magnetic Force and Stiffness in Cylindrical Permanent Magnets and Coils

This article establishes an equivalent model between cylindrical permanent magnets and solenoids. Based on the magnetic charge theory and Coulomb’s model, an expression for the axial magnetic force is derived, and then the dimensionless axial magnetic force formula. Through further differentiation, the dimensionless axial stiffness formula is obtained. An in-depth analysis is conducted on the impact of dimensionless parameters on axial stiffness. The process of dimensionless calculations eliminates interference caused by differences in unit systems, revealing the intrinsic relationship between magnetic stiffness and the geometric and material properties of the magnets. This provides a theoretical basis for the optimization of electromagnetic device design and holds extensive application value in both engineering and scientific research fields.
