in his own world, art let loose with more words of wisdom:

WHY? bECAUSE THE MAGNETIC FIELD LINES FROM A DIAMAGNETIC MATERIAL
SUCGH AS ALUMINUM OR COPPER IS AT RIGHT ANGLES TO THE AXIS OF CURRENT
FLOW WHICH IS NOT THE SAME AS WITH A FERRITE MAGNETIC MATERIAL
so, you should be able to take a compass, a piece of copper wire, and a
piece of steel or iron wire and tell the difference between the material
just by passing a dc current through them?


It certainly is not the same axis as the material that the current is
travelling through! Remember my comments with respect to a pendulum when a
eclipse occures, and the happennings in the Bermuda triangle!

ok, lets make this simple. what is the equation for the vector
representation of the magnetic field around an infinitely long straight wire
made of copper? and what is the equation for it around a wire made of iron?
and how do they relate to the bermuda triangle? show all work, and complete
before the next eclipse.



There's no point in being a smart-ass, Chip. You don't have any better
grasp of electromagnetic theory than anyone else on this newsgroup,
including Art.
