Abstract
The existence of magnetic fields in the discs of spiral galaxies is firmly established by both theoretical and observational studies. However, the galactic gaseous discs are not the only objects of galactic size pervaded by magnetic fields. The fields are also detected in gaseous coronae (radiohalos) of galaxies and even in the intergalactic gas of galaxy clusters. In this chapter we briefly discuss the information, scarce though it is, about these ‘over-galactic’ magnetic fields and views on their origin.
