| Abstract: | Polar coronal plumes are modeled using concentrations of magnetic flux at 1.01R
 , and assuming the field is current-free, or a potential field. Identifying the density enhancement of plumes with magnetic flux concentration produces good agreement between 1.01R
and 1.10R
, for model conditions of a large background magnetic field and a plume separation of 50 000 to 70 000 km at the base. Beyond 1.10R
, both plumes and the potential field diverge very nearly as r
