The paper presents a new efficient technique for the harmonic-balance finite-element modeling of magnetically saturated electromagnetic devices. It is based upon the transmission-line modeling method that leads to a numerical scheme where the field-circuit coupled problem harmonic solutions are obtained iteratively. A superposition principle applies due to the substitution of a fictitious linear material to the nonlinear one. This amounts to significant savings both in computation time and storage requirements. The method is validated by applying it to a two-dimensional voltage-driven model of a three-phase inductor
