We extract the magnetic Sachs and Pauli form factors which give the - transition magnetic moment and the decay rates of baryons. We did not find a signal for the magnetic form factor of the neutral transition , which is suppressed by the U-spin flavor symmetry. As a byproduct, we extract the magnetic form factors and the magnetic moments of and baryons, which give an insight to the dynamics of , and quarks having masses at different scales.
