4seventy,
You would be wise to insist on "seeing" this phenominum, I have been insisting for years and so far all I have gotten is BS and excuses....no one has produced one yet..maybe someday I will see one and then perhaps we can get to the bottom of this thing....but I will never believe soft copper can move steel, that is an impossibility according to some of the great metalurgic minds I have gleened...
