The study of the magnetic fields of the Earth and Sun, as well as those of other planets, stars,
and galaxies, has a long history and a rich and varied literature, including in recent years a …

The interstellar magnetic field strength and density are observed to be correlated, but there
is a large dispersion in this relation. In particular, the magnetic field is often observed to be …

The linear and nonlinear dynamo properties of a class of periodically forced flows is
considered. The forcing functions are chosen to drive, in the absence of magnetic effects …

New developments for hydrodynamical dynamo theory have been spurred by recent
evidence of self-sustained dynamo activity in laboratory experiments with liquid metals. The …

The dynamo action of a time-periodic two-dimensional flow close to integrability is analyzed.
At fixed Reynolds number RM and frequency ω, magnetic structures develop in the form of …

The amplification of magnetic field frozen to a two-dimensional spatially periodic flow
consisting of two distinct pulsed Beltrami waves is investigated. The period α of each pulse …
