Possible interaction between unpolarized and polarized nuclei in long range may provide
a new source for PT-violation. Moody and Wilczek proposed that such force might be
mediated by the axion. A new idea of tabletop experiment searching for such interaction
has been proposed from ARIADNE collaboration including SQUID NMR with polarized
3He nuclei using the metastability-exchange optical pumping (MEOP) method. In this
method, uniform magnetic field is required to produce the polarized 3He gas with a laser
at 1083 nm. We describe the finite element method (FEM) as well as the semi-analytical
approach to generate uniform field to preserve polarization with a number of Helmholtz
Coils compared with each other.
