✦ Synopsis

We present a classification scheme for solar flare models that utilize magnetic free energycurrents. The classification scheme is geometry independent and delineates models into two categories: those models utilizing currents flowing parallel to B and those utilizing currents flowing perpendicular to B. This delineation of drivers allows us to specify what kinds of plasma-magnetic field configurations should be expected for a given current driver. Further, the delineation of drivers will allow us to identify both the strengths and the weaknesses of the various models. * Based on invited talks given at the SERF Workshop (Aug. 13, 1979) and the IAU Meeting of Commission 10 (Aug. 15, 1979) held in Montreal. ** Permanent address.

Theories of solar flares based on the storage of energy (usually as magnetic energy) in the solar atmosphere are shown to be incompatible with observational data. The sunspot energy deficit and the photospheric faculae both involve energy fluxes comparable with the flare requirement ( ~ 3 • 1029 er

We solve the energy equation for the high-temperature (coronal) component of flare plasma for two models of energy input: (i) direct collisional heating by a beam of suprathermal electrons, and (ii) ohmic heating by the beam-neutralizing reverse current.

Previous investigations of return currents driven by suprathermal electron beams in solar flares have been based both conceptually and mathematically on analyses of electron beams in the laboratory environment. However, the physics of laboratory electron beams is fundamentally different from the phy
