We investigate the diffusion of relativistic particles in the presence of a time constant, spatially non-homogeneous magnetic field. We show that the intrinsic dynamical instability of the particle trajectories can provide an important source of non-collisional diffusion even in the absence of time-dependent phenomena and for the simplest possible field structure that still allows microscopic chaos.
