No it does not attract to magnets
For normal wiring (inside homes and businesses), insulated copper is used. For long distance transmission, insulated aluminum is used because it is lighter but still a relatively good conductor.

Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.
No it does not attract to magnets
To stop the conductor from touching adjacent grounded structures.
Most likely insulated copper.

As of June 2011 here are some general scrap copper prices: #1 Copper $3.15/lb #2 Copper $3.00/lb #1 Insulated Copper $1.90/lb #2 Insulated Copper $0.90/lb copper prices do fluctuate on a daily basis with the COMEX, LME and economic supply/demand so check prices often to ensure you are getting properly paid at the scrap yard.

Yes, copper is an element because it consists of one type of atom.
Weight of copper wire is measured by the American Wire Gauge. Determining factors are whether or not it is solid wire, insulated and the area.
