Действительно, согласно закону Ома ЭДС индукции $\mathcal{E}_i = IR$, откуда при $R = 0$ получаем $\mathcal{E}_i = 0$. С другой стороны, $\mathcal{E}_i = -\frac{\Delta \Phi}{\Delta t}$, и из условия $\mathcal{E}_i = 0$ следует $\Delta \Phi = 0$, т. е. $\Phi = \text{const}$. До выключения внешнего магнитного поля плоскость кольца пронизывал магнитный поток $\Phi_0 = \pi r^2 B$. Следовательно, такой же поток будет пронизывать плоскость кольца и после выключения электромагнита.
