It has been emphasized that the obtained Alfven wave
like equation is associated with magnetic monopoles, while the counterpart of Alfven wave
equation plays as electric-plasma waves in presence of electrons.

(29) The Alfven waves
do not develop into shocks, but their nonlinear wave-wave interaction may generate compressive waves which then dissipate their energy by shock formation.

move along the sun's magnetic fields like "waves traveling along a string," Jess explains.
The result, rather than being a collection of papers, is an organized text with a logical order of topics, including accretion discs, discs with magnetohydrodynamic (MHD) turbulence and their response to orbiting planets, mixing at the surface of white dwarf stars, pulsar magnetospheres, magnetic fields in galaxies, self-consistent mean field electrodynamics in two and three dimensions, magnetoconversion, Alfven waves
within the earth's core, turbulence models and plane layer dynamos, planetary and stellar dynamos, convection in rotating spherical fluid shells and its dynamic states, laboratory experiments on liquid metal dynamos and liquid metal MHD turbulence and formation and stability in the solar system.
2), which may be satisfactorily interpreted in terms of an enhanced absorption of downgoing Alfven waves
through the perturbed lower ionosphere.
In extremely powerful flares, CME-associated shock fronts can force overlying ions and magnetic fields to oscillate in traveling waves (magnetohydrodynamic or Alfven waves
) that reach supersonic velocities and trigger similar but slower-drifting and longer-lasting radio emissions from coronal plasma waves (Type II bursts).
Instruments onboard, including those built at University of New Hampshire's Space Science Center, sampled electric and magnetic fields as well as charged particles in Earth's upper atmosphere (ionosphere) that get sloshed back and forth by a specific form of electromagnetic energy known as Alfven waves
Physicists have long thought that a type of vibration in the Sun's magnetic field, known as Alfven waves
, might carry enough energy upward to heat the corona, though some ground-based evidence against this idea was reported last year (S&T December 2007, page 16).
An international team of scientists has discovered that powerful magnetic field ripples, called Alfven waves
, might be driving the solar wind and heating much of the corona.
These "Alfven waves
" could carry energy from the turbulent surface and dump it into the corona.
