Scientific paper

The 'mixing time' theory of magnetic heating of the corona by slow photospheric motion (Heyvaerts and Priest, 1984) is examined. It is suggested that Heyvaerts and Priest neglected certain second-order terms in their calculations of the energy and retained the linear part of the perturbed magnetic field. The revised calculations show a heating efficiency and suggest that dissipation-free, linear evolution of the force-free field of the coronal arcade is impossible. The possibility of reconnecting field lines of the nonlinear force-free field is clarified in terms of the field configuration. It is found that reconnection is most likely at a height equal to about one width of the arcade.
