Steven, One time I was interested in the shapes of fields due to charges and found that superposition applies. So, you can think of a dipole as being the sum of two charges with a given separation. The positive charge either attracts your test charge or repels it depending upon its polarity. The negative part of the dipole does the opposite. At large distances the two equal charges tend to cancel out with the only component showing up being due to the distance between them. It is fairly easy to determine the field when broken into two pieces. Good luck with your pursuit.

Hmmm. Then the sauce is getting thicker for me. ;-) > A dipole type structure has a different law, but that is not what you seem to be talking about. Regarding dipoles, According to Wiki: http://en.wikipedia.org/wiki/Dipole "... The dipole term is the dominant one at large distances: Its field alls off in proportion to 1/r3, [3rd power] as compared to 1/r4 fourth power] for the next (quadrupole) term and higher powers of 1/r or higher terms, or 1/r2 for the monopole term." I don't entirely grok this. Complicating matters, there are different lavors of dipoles - for example, charged dipoles and magnetic ipoles. In the past I've done some finite element method magnetic imulations of magnetic configurations. Interesting stuff. > I suspect that you will need to include the charges that are surrounding the star but not inside if you are to see how the force behaves at a large distance. Agreed.
