| Summary | Magnetic fields are of vital importance in astrophysics and geophysics, playing crucial roles in the dynamics of galaxies, stars (including star formation) and planets (including the Earth), and for magnetic confinement fusion. Magnetohydrodynamics, or MHD for short, is concerned with understanding the nature of fluid flows in the presence of magnetic fields, It therefore combines electromagnetic theory with fluid dynamics. This course gives a basic introduction to MHD, detailing how magnetic fields can have significant effects on the nature of flow fluids, including the important topic of plasma confinement in fusion devices. |
