A class of mathematical solutions is presented for the magnetic structure of a flux rope. These solutions in an orthogonal system of tubal coordinates describe the solenoidal distributions of the magnetic field and electric current in a flux rope. The axis of the flux rope can have a varying curvature and its circular cross sections can have varying radii. The axis can even have a torsion; hence, it does not have to be a planar curve. The boundary conditions for the magnetic field and the electric current require that they are in tangential directions at the periphery. Accordingly, the magnetic force density is in the normal direction at the periphery. In particular, the magnetic force is zero at the axis, where gravitational force must be overcome or balanced by thermal force. Such a model structure is useful in the studies of the dynamics of looplike coronal transients and the equilibria of solar prominences. It shows that the magnetic force is so distributed that the latter affects mainly the lateral motion or equilibrium of mass elements in a flux rope relative to the axis. Hence, the translational motion or equilibrium of a flux rope as a whole in the solar atmosphere is determined mainly by other forces, namely hydromagnetic buoyancy force and gravitational force.
