A Functional for Finite Element Analysis of Low Intensity Magnetic Fields Including Permanent Magnetization Effects

摘要

A functional is presented that is useful in the finite element analysis of low intensity, static magnetic field solutions. The variational principle is written in terms of a scalar potential function and, when minimized, leads to field equations and boundary conditions that characterize a magnetic field--accounting for the presence of current, permanent magnetization, and incident magnetic fields. This variational principle finds applications in the finite element analysis of magnetic field problems. (Author)
