Abstract :
The accuracy of force and torque calculation methods in finite-element (FE) systems for electromagnetic problems is discussed. The various sources of error are examined, and requirements of FE systems for an accurate force and torque calculation are derived. Theoretical evaluations are complemented by test and application results
