| contents | In this work, we calculate the magnetic moments of the $P^{N^{0}}_ψ$ states and $P^{Δ^{0}}_ψ$ states with valence quark content $\bar{c}cudd $ in molecular model, diquark-diquark-antiquark model and diquark-triquark model, as well as the transition magnetic moments in the molecular model. At the same time, we also calculate magnetic moments and transition magnetic moments of $P^{Δ^{++}}_ψ$ states and $P^{Δ^{-}}_ψ$ states in the molecular model as additional products. Our results show that in the diquark-diquark-antiquark model, the magnetic moments of $ λ$ excitation state are usually larger than the magnetic moments of $ ρ$ excitation state. We find some interesting proportional relationships between the expressions of transition magnetic moments. The results provide important insights for future experimental observation of hidden-charm pentaquark states and help to distinguish their inner structures. With these efforts, our understanding of the properties for the hidden-charm pentaquark states will become more abundant. |
