Course description and aims

(1-7) The present and ancient magnetic fields of the Earth and other planets are viewed from various observations and studied applying the fundamental theory. (8-11) Dynamics of solar wind is studied in the framework of fluid physics. (12-15) Interplanetary Magnetic Field (IMF), MHD, shock, and formation of magnetosphere are studied on the basis of minimum plasma physics knowledge.

Student learning outcomes

On th basis of fundamental physics knowledge (mechanism, electronmagnetisim, fluid dynamics), the basic Earth system dynamics and the solar-terrestrial relationship are understood with rigourous mathematica treatment.


Geomagnetism, Planetary magnetism, Rock magnetism
Solar wind, MHD, magnetosphere

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Earth system and solar-terretrial phenomena are lectured mainly to understand physical prosesses there.
