That braided copper wire is Nickel coated copper wire braid.



Its useful as a 'solder sucker' if you put flux on it & then use it to suck up molten solder on a circuit board.
It'll suck solder up about a 1/4 to 1/2 inch. Once its done that, just snip that bit off & keep using it.
Thats a old electricians trick.

I have found a few TVs with Ali degaussing cable, not for a while though.
