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 falls 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 for higher terms, or 1/r2 for the monopole term." I don't entirely grok this. Complicating matters, there are different flavors of dipoles - for example, charged dipoles and magnetic dipoles. In the past I've done some finite element method magnetic simulations 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.
