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.
