Content, Learning Outcome and Preconditions
The most important phenomena in ideal fluid dynamics,
magnetohydrodynamics and plasma physics will be explained in an
visually accessible way using illustrative examples and some
experiments. Examples are the magnetic fields in the solar system,
dynamo effect in the sun, plasma confinement in controlled nuclear
fusion experiments. Apart from plasma and astro physics, the basics of
fluid mechanics and electrodynamics are discussed and revisited:
- solar wind
- dynamo effect
- magnetic forces
- magnetic levitation
- plasma equilibria
- single particle picture / collective picture
- turbulent convection
- conservation laws
- turbulent cascades
After successful participation in this module, the students will be able to:
- understand the magneto hydrodynamic (MHD) equations, their main consequences, and their scope of application
- explain the connection between the motion of individual particles and the MHD equations
- discuss the conditions for stable magnetic equilibria plasmas
- describe the MHD instability mechanisms
- understand the turbulence and turbulent transport in unstable MHD plasmas
No preconditions in addition to the requirements for the Master’s program in Physics.

Learning and Teaching Methods
In the thematically structured lecture the learning content is presented. With cross references between different topics the universal concepts in physics are shown. In scientific discussions the students are involved to stimulate their analytic-physics intellectual power.
In exercises the learning content is deepened and exercised using problem examples and calculations. Thus the students are able to explain and apply the learned physics knowledge independently.
To motivate and for visualization demonstration experiments are shown in the lecture.

Description of exams and course work
There will be an oral exam of 25 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample calculations.
For example an assignment in the exam might be:
- Describe the structure of the solar magnetic field in the heliosphere.
- What magneto-hydrodynamic (MHD) instability mechanisms do you know?
- How fast does the Rayleigh-Taylor-instability grow?
- Under which conditions do stable magnetic equilibria in plasmas occur?
The exam may be repeated at the end of the semester.
