The harmonic balance finite element method (HBFEM) proposed is suited to analyzing the time-periodic magnetic field. An AC magnetic field calculation involving saturation characteristics requires many iterations and the intricate procedures for the time derivative. The procedure of the numerical calculation for a new FEM is intrinsically similar to that for the static nonlinear magnetic problem. The paper describes the formulation for the time-periodic magnetic field problems with any saturation characteristics. The calculations applied to a reactor and an electromagnet verify the formulation of the HBFEM.
