Two current concepts of the electrodynamics spin are considered in comparison. Then the original concept, going back to Poynting, was used to demonstrate the transfer of energy and spin from a plane circularly polarized electromagnetic wave into a conducting medium. A spin tensor is used. The given calculations show that spin is the same natural property of a plane electromagnetic wave, as energy and momentum. The expression for the torque density acting on a conducting medium is given. This expression is an analogy of the Lorentz force density.
Keywords
