ABSTRACT: This paper is introduced the impact of magnetic field on a Non-Newtonian biomagnetic fluid. The stenosis artery with porous media model is used for solving the magnetic field and fluid equations simultaneously. The lump in stenosis artery creates vortexes after it place which disrupt the vessel flow. The external magnetic field is applied to weaken this vortexes and produce uniform flow. Furthermore the magnetic field decreases the shear stress on the artery due to neutralizing the created vortex. Another significant effect of applying magnetic force is declining the pressure in this region such that ten times higher magnetic field intensity from 1011 results 8.6X and 6.5X lower maximum pressure and shear stress on artery walls respectively.
