Convective motions in the photosphere and sub-photosphere may be responsible for generating the magnetic fields that support long-lived quiescent solar prominences. The connection is explored here by solving a Dirichlet problem on a semi-infinite strip where the base of the strip is the photosphere, and the strip extends into a current free corona. Even though the convection is simulated only by a one-dimensional potential prescribed at the photosphere it is found that both Kippenhahn-Schlüter and Kuperus-Raadu type fields are possible.
Key words: supergranulation / convection / prominences
