Lectures, 10x2h on magnetohydrodynamics.

In this course I give an overview of MHD from the practitioner's point of view.

We cover the following:

-Short review of classical electrodynamics
-Physics of plasmas, kinetic theory, derivation of General Ohm’s law
-Alfven waves
-Dynamo, reconnection
-Hydrodynamic and hydromagnetic instabilities (…, MRI)
-Classical examples of instabilities in laboratory
-Classical problems, Hartmann flow
-Numerical simulations of turbulence (hands-on)
During the final part of lectures, the participants will perform numerical simulations in the exercise part od lectures,
studying MHD instabilities with the PLUTO code or other code of their choice.
