MHD Equilibria and Waves

This lecture covers static ideal MHD equilibria, focusing on force-free equilibria with low plasma Beta. It also explores magnetic flux tubes observed on the Sun and the waves in ideal MHD plasma, including Alfvén and magnetosonic waves. The exercises involve deriving relations between magnetic field and current, calculating velocities for a fusion plasma, and understanding shear Alfvén waves as vibrating magnetic field lines resembling guitar strings.
