Work of a time-dependent force: An addendum to "Does the electromotive force (always) represent work?"
Certain subtleties concerning the work done by a time-dependent force field are discussed. In particular, it is explained why such a field cannot be conservative even if it is irrotational and its region of action has the proper topological properties.
This article is an addendum to the published article "Does the electromotive force (always) represent work?" (Advanced Electromagnetics, Vol 4, No 1 (2015), pages 10-15, http://www.aemjournal.org/index.php/AEM/article/view/257).
