Geoffkait, if you know that current flowing induces a magnetic field, why were you asking about how magnets can affect something without mass? Ever run a magnet along a cable attached to your speakers?
What I don't understand is how a constant magnetic field from the magnets can affect noise from EMI or RFI, especially without also affecting the audio signal.
