On the basis of analysis of the mathematical model of the magnetic system rather a general approach is proposed to the solving of the inverse problem, which was written by the Fredholm equation: H(z) = ? SJ(s)G(z,s)ds, z ? U, s ? S. 
It was necessary to define the current density distribution function J(s) and the existing winding geometry for creation of a required magnetic field H(z). In the paper a method of solving those by means of regularized iterative processes is proposed. On the base of the concrete magnetic system we perform the numerical study of influence of different factors on the character of the magnetic field being designed.</abstract><trans-abstract xml:lang="ru">В данной работе решается задача поиска конструкции магнитной системы для создания магнитного поля с требуемыми характеристиками в заданной области. На основе анализа математической модели магнитной системы предлагается достаточно общий подход к решению нелинейной обратной задачи, которая описывается уравнением Фредгольма: H(z) = ? SJ(s)G(z,s)ds, z ? U, s ? S.
Необходимо определить распределение плотности тока J(s), а также расстановку источников тока для создания поля H(z). В работе предлагается метод решения этих задач с помощью регуляризованных итерационных процессов. На примере конкретной магнитной системы проводится численное исследование влияния различных факторов на характер создаваемого магнитного поля.</trans-abstract><kwd-group xml:lang="en"><kwd>magnet systems</kwd><kwd>inverse problem</kwd><kwd>Fredholm equation</kwd><kwd>regularized iterative processes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>магнитные системы</kwd><kwd>уравнение Фредгольма</kwd><kwd>метод регуляризации</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Arsenin V.Y., Tikhonov A.N.
