To find a steady state field reversed configuration, a method is considered for sustaining the diamagnetic plasma current by a seed current externally driven at the field null point. The steady state solution is obtained by solving the one-dimensional fluid equations including equilibrium and transport. It is found that the amount of seed current necessary to maintain a steady field reversal depends strongly on τB/τN, where τB and τN are the magnetic diffusion time and the particle confinement time, respectively. As τB/τN increases, more flux is excluded from the plasma. The steady state solution is applied to a D-T ignited plasma.
