Magnetic Fields in Astrophysical Fluids

This lecture covers the dynamics of astrophysical fluids and plasmas, focusing on the observational status of cosmic magnetic fields, synchrotron emission of cosmic ray electrons, and Faraday rotation. It also discusses dust grain alignment, stability of plasma columns, MHD waves, and instabilities. The lecture delves into the Zeeman effect, magnetic correlation length, and the magneto hydrostatics of plasma columns. Various concepts such as filament eruption on the Sun, kink instability, and dispersion relation are explored through perturbation ansatz and linearized MHD equations.
