The resistive evolution of force-free magnetic fields. Part 2. Relation to anisotropic diffusion
Abstract
We consider the diffusion of a magnetic field in a stationary medium where the electrical conductivity along field lines (σ) differs from that across them (σ), and by showing that in the limit σ/σ → 0 the fields remain force-free, some unusual features of force-free evolution are clarified.
