Journal ArticleDOI
Astrophysical magnetic fields and nonlinear dynamo theory
TL;DR: The current understanding of astrophysical magnetic fields is reviewed in this paper, focusing on their generation and maintenance by turbulence, where analytical and numerical results are discussed both for small scale dynamos, which are completely isotropic, and for large scale dynamo, where some form of parity breaking is crucial.

Flux vortices and transport currents in type II superconductors
A. M. Campbell,J. E. Evetts +1 more
TL;DR: In this paper, the authors considered the effects of lattice rigidity on the summation of pinning forces and showed that a summation based on statistical arguments uses the same approximations and leads to the same results as a dissipation argument.
Journal ArticleDOI
Magnetic clouds and force-free fields with constant alpha
TL;DR: In this paper, a cylindrically symmetric, constant alpha force-free magnetic field model was proposed to explain the types of variations of the magnetic field direction that are observed as a magnetic cloud moves past a spacecraft.
Journal ArticleDOI
Creation and dynamics of knotted vortices
TL;DR: In this paper, a 3D-printed hydrofoils are used to link two smoke rings or tie a single ring into a knot, and high-speed imaging shows how the linked rings spontaneously separate, and the knots are able to free themselves.

MHD stability of Spheromak
TL;DR: In this article, an optimal force-free spherical plasma configuration was analyzed for its MHD stability properties, and it was shown that the spherical ellipse with = k (k independent of ) should be stable against all magnetically driven MHD and resistive tearing modes if surrounded by a conducting wall at about rw/r0 = 1.15.
