Interesting question about Helmholz coils from bc.
The field variation within the coil-enclosed volume is well-known.
In situations where uniformity is important, the coil diameter is large compared to the experimental volume of interest.

Yes, what I meant was determined the error, because the radius of the beam is a sig. portion of the reqion defined by the coils, and the field is constant only to first? order of the distance from the center. How does this affect the error in e/m?
