In this study, the light-cone sum rule method is used to compute the magnetic moments of the hidden-charm pentaquark states by taking them into consideration as the compact pentaquark states with quantum number J P = 1 2 - . We have obtained not only the observed hidden-charm pentaquark states, but also the magnetic moments of the hidden-charm pentaquark states that are likely to be observed. In the analyses, we employ the axialvector–diquark–axialvector–diquark–antiquark and axialvector–diquark–scalar–diquark–antiquark forms of interpolating currents, and distribution amplitudes of the photon to get the magnetic moments of hidden-charm pentaquark states. The numerical results of the magnetic moment acquired employing the different configurations are rather different from each other, this means that there is more than one pentaquark with the same quark content and different magnetic moments.
