© 2015 Elsevier Ltd. In this paper, the effect of a magnetic field on non-Newtonian fluid flow in a lid-driven cavity has been analyzed by Finite Difference Lattice Boltzmann Method (FDLBM). It was assumed that the viscosity of the fluid flow is shear-dependent as the power-law model has been selected for the viscosity of the flow. This study has been performed for the certain pertinent parameters of Reynolds number (Re. =. 100-1000), Stuart number ( N = 0-50) and power-law index (n = 0.6-1.4) as the magnetic field is applied at different inclinations of γ=. 0° and 90°. Results show that the increment of Reynolds number augments the effect of magnetic field on the fluid flow. Furthermore, the drop in the power-law indexes increases the influence of the magnetic field at the inclined angle of γ=. 90°. The greatest effect of the horizontal magnetic field (. γ=. 0°) is observed for the power-law index of n=. 1.
