magnet design

Couple of questions on the nature of magnets with regard to the wiffleball effect. I'm still on my first run through of Forrest Mims' basic electronics book so my knowledgebase is still somewhat low.
- In some of the pictures I have seen of the early design polywell magnets, they were straight copper strands wound into spools, fitted inside the steel casing. Why use straight strands for the spool of wire instead of coils?
- From reading Feynman, is the B-field Bussard mentions simply the magnetic field generated by the magnets? Is the strength and size of the B field mainly dependent on the voltage, current, or overall wattage being used?
Say for the same amount of wattage, would a higher voltage and lower current result in a stronger magnetic field or vice versa? Or do you get the same magnetic field for the same wattage, regardless of how the current and voltage balance out?
