| dc.description | A true energy-momentum tensor is unique and does not admit an addition of a term. The true electrodynamics' energy-momentum tensor is the Maxwell-Minkowski tensor. It cannot be got with the Lagrange formalism. The canonical energy-momentum and spin tensors are out of all relation to the physical reality. The true electrodynamics' spin tensor is not equal to a zero. So, electrodynamics' ponderomotive action comprises a force from the Maxwell stress tensor and a torque from the spin tensor. A gauge non-invariant expression for the spin tensor is presented and is used for a consideration of a circularly polarized standing wave. A circularly polarized light beam carries a spin angular momentum and an orbital angular momentum. So, we double the beams angular momentum. The Beths experiment is considered. | |
