The current article focuses on permeability, uniform suction, and Joules heating as key convective effects influencing heat transmission characteristics in nanofluid magnetohydrodynamics flow on a rotating disk. In contrast to a standard Newtonian fluid, Al 2 O 3 nanoparticle water-based nanofluids are employed. The surface of the disk is also taken as convective. Following the implementation of similarity transformations, the leading equations are converted into a series of ordinary differential equations, which are subsequently solved numerically through the utilisation of the bvp4c MATLAB solver. The behavioural research on heat transmission for different parameter dominance is assessed using graphs. As the permeability parameter increases, the dominance of convective effects leads to increased fluid flow away from the disk, which reduces the radial velocity. Also, on the disk surface, the rate of heat transfer shows a direct relation with the permeability of the disk.
