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!
If you did go to college look up your 101 notes or review the new

David, I am like an ever ready battery, I keep going and going until I
can educate all about how radiation occurs in a scientific fashion to
those who are not educated.
Unless debate points out errors that can be substantiated
I will go on and on and on and....
