Gordon, the May 2002 issue of Conformity magazine had an excellent article on Helmholtz coils. I checked their website but didn't see how to access old issues. If you can't get a copy online I will be glad to FAX you a copy of the article. To put things in perspective we can think about

Surely, someone out there has the vector equations describing the magnetic field iof a classic Helmholtz coil. My vector equations class, being 30+ years ago, is just too dim. I keep getting the derivation wrapped around the axle. The centerline equation, H=0.716NI/r, is readily available;
