Hot QCD medium effects have been studied in the effective quasi-particle\ndescription of quark-gluon plasma. This model encodes the collective excitation\nof gluons and quarks/anti-quarks in the thermal medium in terms of effective\nquarks and gluons having non-trivial energy dispersion relation. The present\ninvestigation involves the extension of the effective quasi-particle model in\nstrong magnetic field limit. Realizing, hot QCD medium in the strong magnetic\nfield as an effective grand canonical system in terms of the modified quark,\nanti-quark and gluonic degrees of freedom, the thermodynamics has been studied.\nFurther, the Debye mass in hot QCD medium has to be sensitive to the magnetic\nfield, and subsequently the same has been observed for the effective hot QCD\ncoupling. As an implication, electrical conductivity (longitudinal) has been\nstudied within an effective kinetic theory description of hot QCD in the\npresence of the strong magnetic field. The hot QCD equation of state (EoS),\ndependence entering through the effective coupling and quasi-parton\ndistribution function, found to have a significant impact on the longitudinal\nelectrical conductivity in strong magnetic field background.\n
