Magnetohydrodynamics is the study of dynamics of electrically conducting liquids. Therefore, for an in-depth comprehension of plasma physics, one must be well acquainted with magnetohydrodynamics (MHD) behaviors. With progresses in science, a gap between state-of-the-art researches and published textbooks slowly develops. An interrelation between textbook knowledge and updated research results can often be hard to develop. Review articles can be of significant help in such cases. For magnetically restricted fusions, toroidal magnetohydrodynamics theory for tokamaks, magnetic relaxation procedure in spheromaks, and the creation and stability of field-reversed configuration have been provided in this book. In-depth descriptions of X-ray jets physics and solar spicules, along with sub-fluid theory have been covered from the vast domain of space plasma physics. For numerical techniques, the definite numerical techniques for resistive MHD and the boundary control formalism have also been provided in this book. Theory of Newtonian and non-Newtonian fluids has also been presented in this book for comprehending low temperature plasma physics.
