Playing with wires, would like to apply a random turbulent force that would make the wires float and twist in space.

This thread provided a good start but leaves a few questions [www.sidefx.com]. The basic set up appears to be piping a geometry SOP and a Noise Field DOP into the Field Force data input. The Field Force has Force Attribute parameter set to N which puzzled me at first, but it looks like the Field Force vectors will be set to the Normal of the input geometry, with the Noise Field acting as a mask or scaling the N vectors.

Is the correct interpretation of what is happening with the Noise Field -> Field Force setup? and how would you get a force whose direction varies from point to point in space with this set up or is there another source for that kind of turbulence? Again, just looking for a way to apply simple turbulence force in DOPs.
