Cosmic Magnetic Fields 2022

Monographic lecture for the GeoPlanet doctoral school in the 2022 spring semester
by Dr. Krzysztof Nalewajko (CAMK PAN).
https://events.camk.edu.pl/event/37/

The lectures will be delivered on Tuesdays from 1 Mar to 14 Jun (no lecture on 19 Apr, 3 May, 17 May - 13 meetings) between 11:15 and 13:00 from the large lecture room at Bartycka 18 and transmitted via Zoom. One lecture (7 Jun) is reserved for participant presentations, the final lecture (14 Jun) is reserved for the exam.

Grading will be based on credit points: no pass (0-59), 3 (60-79), 4 (80-99), 5 (100-150). Credit points can be obtained for solving regularly assigned problems (max 50), presenting a classic paper in a journal-club style (max 50), exam (max 50), individual interview.
