•Addressed non-Newtonian hybrid nanofluid loaded with Fe3O4-Ag dust nanoparticles.•Prescribed Heat flux and prescribed surface temperature of boundary conditions are studied.•Unsteady MHD free convection is considered.•A finite difference approach is implemented to gain the numerical solution. A Comprehensive investigation is conducted on transient magnetohydrodynamics boundary layer flow of non-Newtonian micropolar hybrid nanofluid (Fe3O4-Ag) immersed with conducting micrometer homogeneously sized dust nanoparticles within a stretching sheet adjacent to prescribed surface temperature (PST) and prescribed heat flux (PHF) cases is presented. The mathematical model is formulated then the convenient similarity transformations are implemented on the governing PDEs to get dimensionless system. The non-dimensional flow governing equations have been solved by help of the builtin MATLAB approach named as bvp4c which represents a finite difference method. The outcomes for variant emerging parameters for both micropolar hybrid nanofluid and dust phases are evaluated and provided throughout graphical forms, tables then argued in detail. Authentication of the gained computations is given by comparing with earlier published data. Enhancement in thermal relaxation strengthens temperature variation in both micropolar hybrid nanofluid and dust phases.
