Two oppositely charged particles traveling in opposite directions[Don Simanek]
along parallel paths? Whoops, which kind of "oppositeness" rules?
Hah! got tangled in your rules, eh? They attract, of course
Your point is correct; your example is, unfortunately, ill-chosen.
The reason, of course, is that currents going in the *same*
direction attract, what is known as the "pinch effect". The pinch
effect is itself a fine Gegenbeispiel. In that case "Likes attract."

I suspect it is Leigh who has been caught. One may accept the pinch
effect, but then argue like this:
a moving particle does not have to represent a current.
If oppositely charged particles travelling in opposition attract,
then one could assume that similarly charged particles travelling
in convoy would also attract ( via the double negative ).
