Magnetic fields and the distribution of cosmic rays in the GalaxyIf a galactic origin for the bulk of cosmic-ray particles is assumed, it is the magnetic field which regulates the propagation and escape of the particles from the Galaxy. Questions of the anisotropy of the cosmic-ray flux are considered together with magnetic-field models which can confine the particles and produce low anisotropies. In one standard approach it is postulated that the particles random walk through the presumably irregular magnetic field. In view of the difficulties associated with a diffusion hypothesis other confinement mechanisms have been proposed.
