It is demonstrated that dielectric or magnetic, which absorbs a circularly polarized plane electromagnetic wave, absorbs the angular momentum, which is contained in the wave according to the canonical spin tensor of electrodynamics. Lorentz transformations are used for energy, momentum, and angular momentum flux density because a moving absorber is considered. The given calculations show that spin occurs to be the same natural property of a plane electromagnetic wave, as energy and momentum.
