Re: [Phys-L] e/m apparatus

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.

bc, has complete Busch method from UCB (Coils, 2?BP1, P/Ss), and wonders the % error Peter obtained.

Has anyone calculated the field variation for the Helmholz?
