Current sheets in two-dimensional potential magnetic fields. I - General properties
Abstract
The equilibrium of a set of current sheets embedded in a potential magnetic field is studied as well as some general properties of quasi-potential singular equilibrium (QPSE). Representations were established for an x-invariant magnetic field which is potential everywhere but on a set of singular surfaces. It is shown that, in a QPSE, the current sheets are analytical curves. An analytical curve may always be interpreted as a current sheet embedded in a QPSE.
