  We study systematically magnetic moments of hiddden-bottom pentaquark states
with quantum numbers $J^P=\frac{1}{2}^{\pm}$, $J^P=\frac{3}{2}^{\pm}$, and
$J^P=\frac{5}{2}^{\pm}$ with molecular, diquark-diquark-antiquark, and
diquark-triquark models. The numerical results show that magnetic moments are
different within the same model according to same quantum numbers and
spin-orbit couplings. The results are also different when different models are
taken into account with the same angular momentum. The magnetic moments encode
valuable information about inner structures. We believe that our results may be
helpful for experimental studies.
