When any of the flux tubes that collectively make up a magnetic field continuum is dislocated and misaligned relative to the rest of the field, there is a dynamical steepening of field gradients. Consequently, there is rapid dissipation of the dislocated field no matter how large the electrical conductivity of the medium. This paper presents some formal illustrations of local conditions along a misaligned flux tube, showing the simultaneous onset of diffusion, fluid motion, and hydromagnetic wave propagation. The examples show that the total effect is complicated and subject only to estimation, rather than formal calculation, at the present time.
We suggest that dislocation dissipation occurs in the magnetic fields of active regions on the Sun, contributing to the enhanced corona. Estimates of the dislocation dissipation in the active corona are carried out based on the observed properties of active coronal arches and filaments. The estimates show that the dissipation may contribute a significant portion of the coronal heating. It is pointed out that dislocation dissipation must occur in the active terrestrial magnetosphere and in the active gaseous disk of the Galaxy, although we make no attempt at a quantitative assessment of the rates.
