Scientific paper

Magnetic loop heating of plasmas is studied with a numerical model of fast reconnection in a closed system. The model considers three regions bounded by steady slow and fast shocks. A small local resistivity causes magnetic tearing, which increases plasma flow and thins the current sheet. Plasma entering the second regions can move with supersonic velocity if the upstream slow shock region is sufficiently longer than the following neutral region. However, the supersonic flow may encounter a quickly closing magnetic loop, which presses against the neutral region, reducing its size, and thereby exposes the plasma ions to ohmic heating in the smaller neutral zone. An expression is defined for quantifying the amount of heating that can be expected. The model is intended for modeling plasma heating in solar flares and geomagnetic substorm activity.
