ABSTRACT: 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.
