%X The structure of the magnetic field of the Galaxy and other spiral systems and the inseparable problem of the origin of cosmic rays are examined: (1) A variety of evidence is used to show that the galactic field extends far beyond the disk and connects the disk field with a general field fixed in the local system of galaxies. (2) The coronal field extends beyond 10 kpc as an oblique helix which is constantly expanding, and has partially force·free characteristics.
