The magnetic form factor for the ground state of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ has been measured for momentum transfers $q=0.8-2.8\mathrm{}$ ${\mathrm{fm}}^{-1\mathrm{}}$. The diffraction minimum has been located at $q=1.41\mathrm{}$ ${\mathrm{fm}}^{-1\mathrm{}}$, and the results extend over the second maximum. All available longitudinal and transverse form factors of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ are shown to be consistent with the $\alpha -d$ cluster model providing the $d$ cluster is deformed and aligned. Comparison is made between the elastic and 3.56 MeV $M1$ form factors, and the effects of exchange currents are considered. The ground-state current density is deduced by a Fourier-Bessel analysis of the elastic $M1$ data.
