How do helmholtz coils work

WebIntroduction. Helmholtz coil is named after the German physicist Hermann von Helmholtz. It is comprised of two identical magnetic coils positioned in parallel to each other, and their centers are aligned in the same x-axis. The two coils are separated by a distance equal to the radius like a mirror image as shown in Figure 1. Webdesign of a Helmholtz coil providing the size and shape of the uniform ﬁeld region for a given precision. Low magnitude ac ﬁeld calibration or characterization over an experimental region in space is not a trivial task.
