AbstractA defect of the standard classical electrodynamics is the theory does not know spin. The spin tensor of the classical electrodynamics is zero. The absence of spin in the theory implies an absurd corollary: a circularly polarized plane wave has no angular momentum at all in direct contradiction to quantum theory. An orbital angular momentum of a circularly polarized beam without an azimuth phase structure is erroneously recognized as spin. An expression for electrodynamics' spin tensor is presented.
