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.
