Good stuff, Ed.

Another point is that in the near field of a current source, the 
magnetic field dominates. This is one of the reasons that power control 
electronics, especially those for large motors and solar systems, can be 
so problematic for close-in neighbors, as observed in the QST piece 
several years ago on solar system RFI.
