Resonant Particle Energy Transfer to Magnetic Perturbations with Application to the Geomagnetic Tail

摘要

It is shown how resonant particles can give up their kinetic energy to induced electric fields and hence cause amplification of the perturbed magnetic field energy. This is a simple physical picture of the instability of the sheet pinch. It reveals the nature of the instability and gives some insight into its degree of violence. (Author)
