Popis:	Several writers have proposed quasistatic theories of moving magnetized bodies, neglecting the induced electric fields. Obviously, this excludes the possibility of analyzing radiation, which I can tolerate. However, time independent fields have been observed in some steadily rotating magnetized bodies, in particular. I will review experimental evidence for such cases, paying attention to the observed induced electric fields. It turns out that these tend to be very small in dielectrics, but not in conductors. For the latter, I will suggest a rather simple way of modifying theories to account for them. Also, for more general theories of electromagnetism, I will compare two old schemes, a non-relativistic one due to Maxwell and Lorentz and a relativistic scheme proposed by Minkowski. Among workers interested in continuum theory, the former seems to be more popular, but experimental evidence favors the latter over the former and one modern theory.
