Abstract
 

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.
