Abstract

We establish the existence of axially symmetric weak solutions to steady incompressible magnetohydrodynamics with nonhomogeneous boundary conditions. The key issue is the Bernoulli’s law for the total head pressure $\Phi = \frac{1}{2} ({\lvert u \rvert}^2 + {\lvert h \rvert}^2) + p$ to a special class of solutions to the inviscid, non-resistive MHD system, where the magnetic field only contains the swirl component.
