Abstract

A method for calculating the mutual inductance of a system of tightly wound coils through the energy of axially magnetized cylinders is proposed. Formulas for calculating 3D fields of a cylinder and coils expressed in terms of elliptical integrals are obtained. Тhe volume-average demagnetization factor of the cylinder is shown to be equal to the Nagaoka coefficient for the self-inductance of short coils.

一种利用轴向磁化圆柱模型计算线圈系统互感的方法

摘要

提出了一种通过轴向磁化圆柱体的能量计算紧密绕制线圈系统互感的方法。获得用于计算圆柱体和线圈的3D场的公式，这些公式以椭圆积分表示。圆柱的体积平均退磁系数显示为与短线圈自感的长冈系数相等。
