The static configurations of a long Josephson junction in the presence of an external magnetic field are investigated. The theoretical analysis is based on the phase-space configurations of the perturbed sine-Gordon equation in the time-independent case. The proposed method allows one to compute in a very simple way the dependence of the Josephson current on the magnetic field for arbitrary junction lengths.
