English: An electromagnetic field very far from currents and charges (sources) is called electromagnetic radiation (EMR) since it radiates from the charges and currents in the source, has no "feedback" effect on them, and is also not affected directly by them in the present time (rather, it is indirectly produced by a sequence of changes in fields radiating out from them in the past).
