Abstract

The magnetic moments and transition magnetic moments of the ground-state baryons are analyzed in an expansion in $1/{N}_{c}$, $SU(3)$ flavor symmetry breaking and isospin symmetry breaking. There is clear evidence in the experimental data for the hierarchy of magnetic moments of the combined expansion in $1/{N}_{c}$ and flavor breaking. $SU(3)$ breaking in the magnetic moments is expected to be enhanced relative to that of other hadronic observables, and significant $SU(3)$ breaking is found.
