With an aim to investigate the effect of externally imposed body accelerationand magnetic field on pulsatile flow of blood through an arterial segmenthaving stenosis is under consideration in this paper. The flow of blood ispresented by a unsteady micropolar fluid and the heat transfer characteristicshave been taken into account. The non-linear equations that governing the floware solved numerically using finite difference technique by employing asuitable coordinate transformation. The numerical results have been observedfor axial and microrotation component of velocity, fluid acceleration, wallshear stress(WSS), flow resistance, temperature and the volumetric flow rate.It thus turns out that the rate of heat transfer increases with the increase ofHartmann number $H$, while the wall shear stress has a reducing effect on theHartmann number $H$ and an enhancing effect on microrotation parameter $K$ aswell as the constriction height $\delta$.
