  We study the fluctuation properties of $\Delta T=0$ electromagnetic
transition intensities and electromagnetic moments in $A \sim 60$ nuclei within
the framework of the interacting shell model, using a realistic effective
interaction for
  $pf$-shell nuclei with a $^{56}$Ni core. The distributions of the transition
intensities and of the electromagnetic moments are well described by the
Gaussian orthogonal ensemble of random matrices. In particular, the transition
intensity distributions follow a Porter-Thomas distribution. When diagonal
matrix elements (i.e., moments) are included in the analysis of transition
intensities, we find that the distributions remain Porter-Thomas except for the
isoscalar $M1$. The latter deviation is explained in terms of the structure of
the isoscalar $M1$ operator.
