Abstract

We present a simple model that demonstrates that regions of high current density cannot exist within the solar atmosphere in a quasi-stationary state if they do not already exist at the photospheric boundary. This result demonstrates that theoretical treatments of coronal heating by electrodynamic processes must take proper account of the photospheric spatial distribution of the forces that generate the currents (or equivalently waves) and not just the power contained in those waves that result in coronal heating.
