  We present Quantum Monte Carlo calculations of magnetic form factors in
$A=6-10$ nuclei, based on Norfolk two- and three-nucleon interactions, and
associated one- and two-body electromagnetic currents. Agreement with the
available experimental data for $^6$Li, $^7$Li, $^9$Be and $^{10}$B up to
values of momentum transfer $q\sim 3$ fm$^{-1}$ is achieved when two-nucleon
currents are accounted for. We present a set of predictions for the magnetic
form factors of $^7$Be, $^8$Li, $^9$Li, and $^9$C. In these systems, two-body
currents account for $\sim40-60\%$ of the total magnetic strength. Measurements
in any of these radioactive systems would provide valuable insights on the
nuclear magnetic structure emerging from the underlying many-nucleon dynamics.
A particularly interesting case is that of $^7$Be, as it would enable
investigations of the magnetic structure of mirror nuclei.
