MAS422 Magnetohydrodynamics

Semester 2, 2021/22 10 Credits
Lecturer: Dr Yi Li Reading List
Aims Outcomes Teaching Methods Assessment

Magnetohydrodynamics has been successfully applied to a number of astrophysical problems (e.g., to problems in Solar and Magnetospheric Physics), as well as to problems related to laboratory physics, especially to fusion devices. This module gives an introduction to classical magnetohydrodynamics. Students will get familiar with the system of magnetohydrodynamic equations and main theorems that follow from this system (e.g., conservation laws, anti-dynamo theorem). They will study the simplest magnetic equilibrium configurations, propagation of linear waves, and magnetohydrodynamic stability.

Prerequisites: MAS222 (Differential Equations); MAS280 (Mechanics and Fluids)
No other modules have this module as a prerequisite.
