Попытки применения общей теории относительности для построения электродинамики вращающихся систем пока не привели к общепризнанной теории. Разные авторы получают разные системы уравнений электродинамики во вращающихся системах отсчета и разные модели электрического поля вращающегося магнита. Эти модели можно тестировать в экспериментах с вращающимися магнитами. В работе выполнен эксперимент по проверке двух моделей электрического поля вращающегося намагниченного шара. Теоретические модели предсказывают разные значения электрического потенциала униполярной индукции на полюсе и экваторе шара относительно бесконечности. В эксперименте выполнены прямые измерения потенциала полюса и экватора вращающегося намагниченного шара относительно заземленного экрана. Результаты эксперимента противоречат квадрупольной модели и соответствуют модели электрического поля, получаемой применением преобразований Лоренца для векторов поля, как внутри шара, так и вне его.</p></abstract><trans-abstract xml:lang="en"><p>The phenomenon of unipolar induction is closely related to the problem of electrodynamics of rotating reference frames. Attempts to apply the general relativity theory to construct the electrodynamics of rotating systems have not yet led to a universally recognised theory. Various authors derive different systems of electrodynamics equations in rotating reference frames and different models of the electric field of a rotating magnet. These models can be tested in experiments with rotating magnets. In this work, an experiment is performed to test two models of the electric field of a rotating magnetised sphere. The theoretical models predict different values of the electric potential of unipolar induction at the pole and equator of the sphere relative to infinity. In the experiment, direct measurements of the potential of the pole and equator of a rotating magnetised sphere relative to a grounded screen are performed. The experimental results contradict the quadrupole model and correspond to the electric field model obtained by applying Lorenz transformations for the field vectors both inside and outside the sphere.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>униполярная индукция</kwd><kwd>намагниченный шар</kwd><kwd>магнитный момент</kwd><kwd>вращение</kwd><kwd>теория относительности</kwd><kwd>электрическое поле</kwd><kwd>электрический потенциал</kwd><kwd>магнитное поле</kwd><kwd>электрический квадруполь</kwd><kwd>емкостной зонд</kwd></kwd-group><kwd-group xml:lang="en"><kwd>unipolar induction</kwd><kwd>magnetised sphere</kwd><kwd>magnetic moment</kwd><kwd>rotation</kwd><kwd>relativity theory</kwd><kwd>electric field</kwd><kwd>electric potential</kwd><kwd>magnetic field</kwd><kwd>electric quadrupole</kwd><kwd>capacitive probe</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Пановский, В.
