|In this paper we propose an approach for the de-termination of static force characteristic of a plunger-type AC electromagnet using 2D numerical model developed in QuickField software and the determination of the thermal field. The attraction electromagnetic force is calculated us-ing Maxwell stress tensor method. The magnetic numerical model is an AC magnetics problem coupled with the coil electric circuit. The magnetic numerical model has been experimentally validated. The thermal field is determined in steady-state regime. The source term in the thermal model equation is calculated from the magnetic model data.
