RE: So what's the deal with CD demagnetizers?

Posted by geoffkait on March 22, 2016 at 14:37:15:
Even if aluminum is slightly magnetic due to impurities or is paramagnetic, paramagnetism can't be the general theory of operation since demagnetizers work on vinyl records as well, as vinyl is not magnetic or paramagnetic disregarding any impurities. It should also be mentioned the aluminum layer were talking about is extremely thin. You can actually see through the metal layer sometimes. So there's just not enough aluminum there. Also, demagnetizing CD works for gold CDs which one assumes are not paramagnetic, your theory doesn't seem to apply, nor to CDs that are silver, nickel, copper alloys. Paramagnetism also doesn't explain why demagnetizing interconnects improves the sound.
