Motion of charged particle. Fundamental of magnetohydrodynamic (MHD) equation. Nature of collisionless plasma. Structure of magnetifc field. Plasma waves. Physcal processes for these topics will be studied.
We study fundamental plasma processes in collisional cosmic hot ant tenuous plasma. The main topic is plasma dynamics in the context of MHD on th basis of already-stuied classical mechanism, classical electrodynamics, and fluid dynamics. Weshould know the basic difference between fluid dynamics and collisionless plasma fluid treatment.
Motion of charge particle in simplified electromagnetic field structure. MHD. MHD stability. MHD waves. MRI.
plasma, magnetohydrodynamics.

There are a lot of newly published plasma textbooks in undergraduate and graduate levels.
Several examples are presented as problems. These problems will be studied as reports.
