- In this work, the electromagnetic structure of the hidden-charm pentaquark $P_c(4337)$ is investigated within the diquark-diquark-antiquark model using the QCD light-cone sum rule approach. The magnetic moments of the $ P_c(4337) $ state are calculated for the spin-parity assignments $ J^P = \frac{1}{2}^- $ and $\frac{3}{2}^-$. The results are found to be $ μ_{P_c} = 1.76 \pm 0.44~μ_N $ for the $ \frac{1}{2}^- $ case and $ μ_{P_c} = -1.38 \pm 0.35~μ_N $ for the $ \frac{3}{2}^- $ scenario. These findings offer important insights into the internal quark-gluon structure and electromagnetic features of this multiquark system. Beyond their theoretical relevance, the results serve as essential benchmarks for future experimental studies aimed at determining the quantum numbers and underlying configuration of the $ P_c(4337) $. Additionally, the electric quadrupole and magnetic octupole moments of the spin-$\frac{3}{2}$ state are extracted, indicating a non-spherical charge distribution for this exotic pentaquark.
