FTP what are these ion-carried waves commonly described as the result of "plucking" the magnetic field lines in a plasma, named for their Swedish formulator?
_In the solar wind they can have wavelengths on the scale of an Earth radius giving a long-scale coherence of them that play a significant role in magnetosphere-ionosphere coupling. First postulated to explain the sunspot cycle, (*) they have been used in the heating of Tokamak plasmas by perturbing the magnetic field in the plasma. The compressional variety is often called a magnetosonic wave and these waves are often derived using the equations of ideal magnetohydrodynamics.
