Im not quite sure how this pertains to any newsgroups, but I think I should
say... um.. Your quite wrong Mr. Wizard.  What your just described
above is the electric force.  Now while related to magnetism (Maxwell's
laws) they are not one and the same.  Iron has zero net charge (usually)
but it does have a magnetic moment, due to the motion of the charges
within the atom.  If all of the magnetic moments of a piece of iron
(all the atoms) align, you have a very strong magnet because magnetic
force is long ranged.  Now while I could go much farther into the nature
of the magnetic force, it would neither make sence to most of you or 
make a point, so I wont.  For that matter, "proving" it would be extremely
difficult, since it would be necessary to isolate it from the other forces.
