If you have a question about this talk, please contact Dr Lara Silvers.

The focus of this review of galactic magnetic fields is on unresolved problems. I will make an attempt to isolate the most physically important problems (the choice, however, remains subjective), briefly present earlier attempts to solve them, discuss why those attempts have not been convincing, and suggest what can we gain from solving these problems. The problems involved range from the dynamics of the multi-phase interstellar medium, to the disc-halo connections in spiral galaxies and their effects on galactic magnetic fields, and to the constraints from magnetic helicity conservation.
