Abstract	A method is proposed to calculate the thrust of a magnetic actuator that operates in the nonlinear magnetic region. The magnetic force expression of the Maxwell stress tensor is expanded to cover magnetic saturation by using a successive approximation of the surface force on the magnetizing curve. The resulting improved finite-element method (FEM) approximation is applied to calculate the thrust of an automotive solenoid valve which operates in the high flux density region near saturation. The calculated values obtained from the improved FEM are in better agreement with the experimental values than the usual linear approximation using the Maxwell stress tensor.<>
