I picked up around 25 yards of cable on the side of the road and I started to strip it when I realized I didn't know what I had grabbed.

The cable has a black plastic outer layer.
a layer of silverish tape.
a mesh of what I think is aluminum
surrounding a layer of white plastic and
in the middle a fairly stiff red copper looking wire that is magnetic.

The cable width is around 1 cm.



I'm new to this stuff so any insight would be appreciated. What kind of cable is it. What is it worth by metal etc.
