But it is true if the wires are twisted 1, 4 or 16 times per inch. Why does twist help? OK I just figured it out. if you look at the e-feild at a point some distance from the wire pair and the pair is twisted you can integrate the field in the direction of the wire (in a plane parallel to the cable and e-feild at d is truly zero. It is way hard to symbolically but way easy using numeric integration. The results are pretty dramatic. I can see why every new kind of data cable uses this.
