Abstract

Formulae are given for the magnetic field strength H of a Helmholtz system of two circular coils. The components of H along and perpendicular to the axis are expressed in series of spherical harmonics which converge rapidly in a region around the centre of the system.
The formulae are normalised, and thus applicable to systems of any size.
The results given in this Report are well known; they have been put together for easy
reference.
