We propose a qualitative explanation for the light radial profile of a spiral galaxy based on the quantitative magnetic model of truncations (Battaner et al. 2002) in which when stars are born (hence the magnetic force acting on the progenitor gas cloud is no longer at work) migrate to larger orbits or escape.
