【 摘 要 】

Existing global models for flares do not include an essential ingredient in the electrodynamics: the inductive electric field due to the time-varying magnetic field. How the large (1010V) electromotive force and the current it drives can be included in a model is discussed. Alfve´n waves play an important role in transporting energy and potential, and in redistributing current on a global scale.
