The behaviour of long Josephson junction surveyed at course through it of a constant electric current. It is established, that behaviour of allocation of a current in long Josephson junction analog to behaviour long elastic rods-cantilevers at a buckling. Besides it is shown, that curls of a magnetic flux penetrating into the one-dimensional junction are analog of a line-up of spins in an external field which orientation depends on a relation of a natural and exterior magnetic field, i.e. long Josephson junction can be considered as dynamic domain structure.
