Spay for CD

A couple things, I just found, that may be of interest to some(SORRY again, OP): https://www.youtube.com/watch?v=cYA0bntrjsk(comments notwithstanding) and https://www.youtube.com/watch?v=wMFPe-DwULM(I love this guy!)

What magnetism is composed of is irrelevant. All you need to know is that demagnetizing CDs or LPs improves the sound, or interconnects. So I guess we can close this case. 

I couldn’t agree more! Regarding my last post: I just thought you may be interested, in what your favorite physicist(my assumption) had to say on the matter! You did pose the question, " Just one more thing. The web site you linked to edu Illinois Physics forum of some kind, as I recall, made some statements that magnetic fields were composed of photons. Since magnetic fields are stationary how can they be composed of photons that move at lightspeed?"

Actually, I find him trite and defensive. He could have explained that the atoms of magnetic material like magnets are aligned N to S or whatever and that nuclear forces are the STRONGEST force or whatever. Whereas as gravity is the WEAKEST force. This attitude of his is why he was ostracized when he was a member of the Rogers Commission investigating the Challenger disaster. I knew the guy who ostracized him, who was the director of the commission.

None of which explains OF WHAT magnetism is MADE, but-  "All you need to know is that demagnetizing CDs or LPs improves the sound, or interconnects." and: AMEN(no offence)!  Happy listening!
