本文用非相对论方法研究了运动磁化介质中的等效极化Peq=（1/c2）v×Meq。本文采用类似于Panofsky和菲利普斯的方法，计算运动极化介质的对称效应，即等效磁化强度Meq=P×v。这种方法是基于麦克斯韦方程的特殊表达式和对流导数的应用。然而，这些作者认为，等效极化只能用相对论方法获得。我们表明，使用相同的方法，但使用麦克斯韦方程组的不同且等效的表达式，也可以计算这种效应。这样，两种效应都可以被认为是v/c中一阶的相对论效应。
We present a non-relativistic approach to the equivalent polarization Peq=(1/c2)v×Meq, that appears in a magnetized medium in motion. We apply an analogous method to that used by Panofsky and Phillips to calculate the symmetric effect, the equivalent magnetization that appears in a polarized dielectric in motion, Meq=P×v, This method is based on a particular expression of Maxwell’s equations and the application of the convective derivative. These authors argue, however, that the equivalent polarization can be obtained only with a relativistic approach. We show that with the same method, but with a different and equivalent expression of Maxwell’s equations, this effect can also be calculated. In this way both effects can be considered relativistic effects to first order in v/c.
