   <abstract xml:lang="ru">
    <p>Представлены и обсуждаются свойства следующих моделей магнитного поля в магнитном облаке: решение Миллера–Тернера, модифицированное решение Миллера–Тернера, тороидальная и интегральная модели Ромашеца–Вандаса, модель Криттинама–Руффоло. Магнитное поле во всех моделях обладает винтовой структурой, что является главным признаком магнитного облака. Первые три модели описывают магнитное поле внутри заданного идеального тора. В интегральной модели параметры образующего тора неоднозначно определяют объем и форму области, занятой магнитным полем. В модели Криттинама–Руффоло радиус сечения тора имеет переменное значение, что лучше соответствует реальной форме магнитных облаков во внутренней гелиосфере. Модели могут быть использованы при интерпретации прямых измерений компонент магнитного поля, изучении форбуш-понижений в магнитных облаках и исследовании распространения солнечных энергичных частиц, сопровождающих выбросы коронального солнечного вещества.</p>

    <p>We present and discuss properties of the following magnetic field models in a magnetic cloud: Miller and Turner solution, modified Miller–Turner solution, Romashets–Vandas toroidal and integral models, and Krittinatham–Ruffolo model. Helicity of the magnetic field in all the models is the main feature of magnetic clouds. The first three models describe the magnetic field inside an ideal torus. In the integral model, parameters of a generating torus ambiguously determine the volume and form of the magnetic field region. In the Krittinatham–Ruffolo model, the cross-section radius of the torus is variable, thereby it corresponds more closely to the real form of magnetic clouds in the inner heliosphere. These models can be used to interpret in-situ observations of the magnetic flux rope, to study a Forbush decrease in magnetic clouds and transport effects of solar energetic particles injected into a coronal mass ejection.</p>
