本文详细分析了半无限平板外的圆形电流在平板内产生的涡流。特别注意的是板坯外的磁场，并解释的条件下，图像的方法可以安全地应用。计算了平板的有效阻抗，并与最近的实验结果进行了比较。的应用程序的工作的旋转机器的端场进行了讨论，它示出的端部绕组的直径和端板的饱和度的涡流行为有深远的影响。
The paper contains a detailed analysis of the eddy currents induced in a semi-infinite slab by a circular current outside the slab. Particular attention is paid to the magnetic field outside the slab, and the conditions are explained under which the method of images can be safely applied. The effective impedance of the slab is calculated, and the results are compared with recent experimental work. The application of the work to the end-fields of rotating machines is discussed, and it is shown that the diameter of the end-windings and the degree of saturation of the end-plates have a profound effect on the eddy-current behaviour.
