The radiative decays of $B^{\mathrm{*}}$ mesons are studied using a confined Coulombic model for heavy-light-quark bags, which contains also the effects of pion-exchange currents. The calculated widths of the $B^{\mathrm{*}}$→Bγ decay modes come out smaller than in simple quark models and in other previous calculations. The consequences of a possible anomalous magnetic moment of the b quark are mentioned.
