Explosive Coalescence of Magnetic Islands

IEEE Transactions on Plasma Science, 1986
An explosive reconnection process associated with nonlinear evolution of the coalescence instability is found through studies of particle and magnetohydrodynamic (MHD) simulations. The explosive coalescence is a self-similar process of magnetic collapse, in which the magnetic and electrostatic energies and temperatures explode toward the explosion time

Magnetic Island

2021
Al largo della città di Townsville, in Australia, c'è quella che deve il suo nome alle anomalie registrate sulle bussole dal capitano James Cook nel 1770, mentre navigava in zona. Ma di "isole magnetiche" si parla anche in fisica nucleare e, in particolare, nella fisica del plasma, noto anche come quarto stato della materia. Ne scopriamo l'importanza

Macroscopic Coherent Magnetic Islands [PDF]

, 2001
We present experimental and theoretical investigations on the dynamics of coherent magnetic islands in high temperature, magnetically confined plasmas of thermonuclear interest, and of their effects on plasma transport.

Magnetism in Heard Island rocks

Journal of Geophysical Research, 1965
The directions of remanent magnetization in igneous rocks from Heard Island show both negative and positive polarities. Their mean, irrespective of sign, is close to the hypothetical axial geocentric dipole field but differs from it by an amount which is about equal to the error in the determination. This divergence may not be real and requires further

Reconnection of coalescing magnetic islands

Physics of Plasmas, 1999
The dynamics of magnetic reconnection in the framework of two-dimensional incompressible magnetohydrodynamics is studied numerically. The case of a doubly periodic array of magnetic islands where coalescence of neighboring islands occurs due to self-consistent magnetic forces is investigated.

Self-excitation of magnetic islands

Nuclear Fusion, 1994
A mechanism of island self-excitation is discussed in detail, by studying the dynamical interaction, in a tokamak plasma, of a suitably defined ensemble of ions with the electrostatic field of densely packed island chains, assuming that the ion Larmor radius is larger than the island width.
