      abstract     = {Results of a measurement of dimuon photoproduction in
                      nonultraperipheral Pb+Pb collisions at $\sqrt{s}_{NN}$ =
                      5.02 TeV are presented. The measurement uses ATLAS data from
                      the 2015 and 2018 Pb+Pb data-taking periods at the LHC with
                      an integrated luminosity of 1.94 nb$^{−1}$. The $γγ →
                      μ^+μ^−$ pairs are identified via selections on pair
                      momentum asymmetry and acoplanarity. Differential cross
                      sections for dimuon production are measured in different
                      centrality, average muon momentum, and pair rapidity
                      intervals as functions of acoplanarity and $k_⊥$, the
                      transverse momentum kick of one muon relative to the other.
                      Measurements are also made as a function of the rapidity
                      separation of the muons and the angle of the muon pair
                      relative to the second-order event plane to test whether
                      magnetic fields generated in the quark-gluon plasma affect
                      the measured muons. A prior observation of a
                      centrality-dependent broadening of the acoplanarity
                      distribution is confirmed. Furthermore, the improved
                      precision of the measurement reveals a depletion in the
                      number of pairs having small acoplanarity or $k_⊥$ values
                      in more central collisions. The acoplanarity distributions
                      in a given centrality interval are observed to vary with the
                      mean $p_T$ of the muons in the pair, but the $k_⊥$
                      distributions do not. Comparisons with recent theoretical
                      predictions are made. The predicted trends associated with
                      effects of magnetic fields on the dimuons are not observed.},
