I don't think "shield fairly well" paints an accurate
picture of what it could do.
"Might reduce magnetic flux in a small area around the loop
axis " would be a better description.
I can't imagine anyone doing that for lightning protection.
You'd be better off burying the copper and using it for a
ground if lightning protection is the goal.
