Transportation of hybrid ferrofluid has been illustrated in the current article with the imposition of Lorentz forces. A numerical approach with the help of vorticity formulation was involved. Outputs demonstrate the opportunity to manage the thermal behavior with the magnetic field. As Lorentz force is imposed, the strength of eddies reduces and velocity of nanopowders reduces. Reductive impact of Hartmann is ignorable in the lower permeability, but it becomes stronger with the rise in Da. As Rd enhances, isotherms become more disturbed and higher Nu is obtained. Unfavorable effect of permeability on the thickness of boundary layer makes Nu to increase, and a similar impact was demonstrated for buoyancy force.
