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.
The diameter of an insulated 750 MCM copper wire is 1.25 inches. The insulated 750 MCM copper wiring has 61 strands and has a weight of 2.7 pounds per foot.
No it does not attract to magnets

So the wire doesn't short itself out. The electricity needs to go through all the windings individually.

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.
Standard Romex is a three-strand, solid core wire, individually insulated, in a common sheath to make it easier to pull. For a short time, some manufacturers were making romex with aluminum because the cost of copper was so high, but the aluminum wire was not as good as the copper, and the practice was discontinued.

To stop the conductor from touching adjacent grounded structures.
Most likely insulated copper.
