Abstract

It is shown that Evans' proposal of an axial magnetic field associated with a circularly polarized light wave or photon in free space cannot be correct because it would violate charge conjugation symmetry. However, an axial magnetic field induced by a circularly polarized light wave in an atomic or molecular medium conserves charge conjugation symmetry, being observed as the inverse Faraday effect.
