• In the earlier paper we treated a magnetohydrodynamic equilibrium of a long plasma cylinder by making use of the London equation and found that the plasma cylinder is almost confined in the radius of the several times the penetration depth r<SUB>0</SUB> (= (m<SUB>e</SUB>/μ<SUB>0</SUB>n<SUB>0</SUB> e<SUP>2</SUP>) <SUP>1/2</SUP>). We shall here discuss an equilibrium configuration of a ring form plasma, using the toroidal coordinates (r, ν, ψ) in which j<SUB>r</SUB>=B<SUB>r</SUB>=O (where j is the current density and B the magnetic field). Numerical calculations show that profiles of equi-macroscopic quantity, just as the equi-number density, the equi-magnetic field and so on, are shifted from the center of tube towards away from the ring axis.
