We present recent Green's function Monte Carlo calculations of magnetic moments and M1 transitions in A{<=} 9 nuclei, which include corrections arising from two-body meson-exchange electromagnetic currents. Two-body effects provide significant corrections to the calculated observables, bringing them in excellent agreement with the experimental data. In particular, we find that two body corrections are especially large in the A = 9, T = 3/2 systems, in which they account for up to ~ 20% (~ 40%) of the total predicted value for the {sup 9}Li ({sup 9}C) magnetic moment.
