本文介绍了一种在旋转磁场中测量电工钢片磁场矢量的装置。为了避免复杂的涡流效应，我们产生了一个旋转的B-矢量具有恒定的模量和角速度。在一个旋转周期内，在无取向的硅铁样品中观察到磁场强度的模量以及\vec{B}和\vec{H}之间的角度的相当大的变化。关于旋转损耗的结果与用不同的技术测量的结果吻合得很好。
An apparatus is described which is used to measure the magnetic field vectors in electrical steel sheets in rotating magnetic fields. To avoid complicated eddy current effects we produce a rotating B-vector with constant modulus and angular velocity. Considerable variations of the modulus of the magnetic field strength and of the angle between \vec{B} and \vec{H} during one period of rotation are observed in a sample of non-oriented silicon iron. The results concerning the rotational losses are in good agreement with these measured with a different technique.
