Abstract
The definition of angular momentum (AM) in electrodynamics is re-examined, so as to cover charged and infrared fields as well. The total AM is identified as that outgoing in the future or incoming from the past causal directions respectively. For these representations to be equivalent, a certain condition must be satisfied; it is fulfilled in the usual field-theory context but excludes magnetic monopoles. In the presence of charges, the total AM cannot be completely separated in remote past or future into free matter and free electromagnetic field parts, which should have consequences in quantum theory.
