Understanding the screening mass of pseudoscalar mesons at finite temperature and magnetic field is crucial for comprehending behavior strongly interacting matter under extreme conditions, such as those found in early universe or inside neutron stars. Additionally, heavy ion collisions, strong fields are generated, which could significantly influence properties quark-gluon plasma. The study these masses provides insight into modifications mesonic environments, essential theoretical understanding Quantum Chromodynamics (QCD) phase transitions Here, we present continuum estimated lattice QCD results on neutral temperatures nonzero fields. simulations used (2+1)-flavor using physical quark employing HISQ/tree action. estimation was carried out lattices having temporal extents $N_\tau$ = 8, 12, 16, all aspect ratio $N_\sigma/N_\tau$ 4. investigated ranges from 145 MeV to 166 MeV, while strength varies 0 1 GeV$^2$. We discuss dependence various temperature, strength, mass.
