As I pointed out in a previous post, the differential term is zero in the
absence of one of the fields so the equations have no, non-trivial,
solutions.

That was not what you said before, and now you are attempting to change
history
in order to save face. You said that for static fields there were no
non-zero differential
results and you poured scorn not only on my background, but also on Essex
University where I studied.

And here is the evidence of your attempt to rewrite history in order to save
face,
coupled once again with your uncontrollable urge to make nasty comments
in passing (Why do you behave like that?) ...

-----ooooo-----

Of course, regardless of the day of the week, Maxwell is much good for a
static field. (Differential = 0).
The appalling lack of mathematical ability shown by some who claim degrees
in engineering really makes you wonder at times. Especially as that would
have been in a maths
qualification required for any decent Uni. entry.
