Electromagnet math! Mathematicians and Electricians get in here!!

So I have a 55 gallon barrel wrapped with approximately 930 feet of a communications wiring. It is 12 strands of 24 gauge wire. I am trying to figure what the approximated gauge all 12 individual strands together would be equivalent to.

Tesla walks into a bar, the mood changes.

I am essentially trying to create an emp generator. Can this put out anything significant or is the length of wire too long? Thinking DC power source. Having a hell of a time dealing with voltage drop and the initial figures of what guage 12 24 strands equals.
