Abstract: The magnetic moments of the $$B_c$$ B c mesons provide significant insights into their inner structure and geometric shape. Furthermore, a comprehensive understanding of the electromagnetic characteristics of $$B_c$$ B c mesons is essential for advancing our knowledge of confinement and heavy flavor effects. In light of this, we proceed to extract the magnetic moments of the ground-state vector and axial-vector $$B_c$$ B c mesons through the medium of the QCD light-cone sum rules. The magnetic moments of the axial-vector and vector $$B_c$$ B c mesons are found to be $$\mu _{B_c}= -0.47 \pm 0.07~\mu _N$$ μ B c = - 0.47 ± 0.07 μ N , and $$\mu _{B_c}= 0.15 \pm 0.02~\mu _N$$ μ B c = 0.15 ± 0.02 μ N , respectively. A comparison of our results for the vector $$B_c$$ B c meson with other theoretical predictions has revealed discrepancies between the various predictions, which could prove useful as a complementary tool for interpreting the vector $$B_c$$ B c meson. The current experimental data set is limited to a small number of observed states of beauty-charm mesons. However, theoretical studies can play a valuable role in elucidating their nature and guiding future experimental investigations.
