Magnetic Vortex Tubes in Astrophysics

Abstract

The viscous forces on electrons and ions in a differentially rotating plasma drive an azimuthal current density j¿, with axial magnetic field Bz which is shown to be proportional to plasma vorticity. Field strengths in agreement with those observed for both stars and galaxies are obtained, assuming that reactive forces prevent radial drifts of electrons or… (More)
