Frozen flux violation, electron demagnetization and magnetic reconnection

Collisionless Reconnection and Electron Demagnetization

Observable, dimensionless properties of the electron diffusion region of collisionless magnetic reconnection are motivated and benchmarked in two and three dimensional Particle In Cell (PIC) simulations as appropriate for measurements with present state of the art spacecraft. The dimensionless quantities of this paper invariably trace their origin to breaking the magnetization of the thermal el...

Electron demagnetization and collisionless magnetic reconnection in e TM 1 plasmas

Abrupt, intense electric field enhancements EFEs with E 100 mV/m surveyed over 3 years of NASA’s Polar spacecraft data are used to illustrate the occurrence and locales of nonguiding center demagnetization of thermal electrons in strongly inhomogeneous electric fields. A lower bound E* a on the perpendicular electric strength sufficient to cause nongyrotropic effects on the electron pressure te...
