"Geoffkait, if you know that current flowing induces a magnetic field, why were you asking about how magnets can affect something without mass?"
I mentioned the fact that current induces a magnetic field just to show that there is already a magnetic field where the signal in running through the wire, that there is no reason for the special alloy to introduce a magnetic field, which is what one poster surmised. I asked how magnets can affect something without mass like an audio signal because unless the signal is affected by the magnets what's the point of the magnets?

Yes, I have. What do you think the magnet is doing in that particular case?

Actually I don't think your statement is true Re the magnetic field and RFI/EMI. I think that's a separate issue. Mu metal is for (absorbing) magnetic fields, you know, what with the permeability but you need AB5100S or some other way to deal with RFI/EMI which is very high frequency electromagnetic waves, as opposed to magnetic fields.
