A convenient toolkit for specifying such windings has been developed. The problems are discussed which arise at the magnetic field calculus from the current elements by using Biot-Savart law. The numerical methods taking into account the singularity of the applied integral equations are suggested.integral equationsBiot-Savart lawcurrent windings modelingинтегральные уравнениязакон Био-Саварамоделирование токовых обмоток
