Hi Gusser,Thanks! Yes, it is an uphill struggle with some of these guys.
The debate with cleantimestream is hampered by the fact that he simply won't define terms, and won't attempt to explain his argument, resorting instead to bluster and insults. The key question, really, is what does one mean by "how magnetic" a non-permanently magnetised material like copper or silver is? I think a reasonable definition, and I suspect the one that he really might have in mind too, is the magnetisation M induced by putting the object in an external magnetic field. It is the quantity that measures how much the substance is reacting to the external field; how much it is being affected by the external field.
But then, it is clear that the one with the greater strength of magnetisation is the one whose absolute value of susceptibility is larger. I think he is getting confused by the fact that the objects here are diamagnetic, and so the susceptiblities are negative. I think maybe he has somehow decided that because they are negative, he should turn the ratio upside down...
But if he would only (a) give his definition of "magneticness", and (b) present his calculation, it would all become instantly clear.
Oh well...

to simplify this.
in the units being discussed:
negative numbers going away from zero are diamagnetic and are repelled by a magnet. the larger the negative number, the more the magnetic field has an effect.
zero represents no effect by a magnetic field (an ideal vacuum)
positive numbers represent paramagnetic which are attracted to magnetic fields.
therefore the larger the number on either side of zero, the more effect the magnetic field has.
I would love to see some documentation on what the net result of this effect is in conductors.

Hi Dave,
Absolutely! Nicely summarised.
Chris
Yes, thanks Dave.
Even I understood that. :-)
But, as Dave asked, what difference does it make in a wire's ability to conduct audio signal?
That's the question!
