Abstract: The effect of magnetic field on blood flow is a very significant topic for bio-medical engineers as the ferrofluids are widely used nowadays in the industry and medicines. The ferrofluids are used as magnetic separation tool, anti-cancer drug carrier, micro-valve application, etc. One important application of these fluids is in chemotherapy application. Besides, the magnetic field can control the heat and blood flow characteristics through the arteries. It has an effect on the resistance to blood flow through arteries. Thus, in this paper, the effect of magnetic field on blood flow through arteries has been discussed. The most recent findings from various research articles are described herein in a systematic way. Moreover, some important results from the articles are presented here. It is observed that the blood flow resistance in a vessel is mainly regulated by the vessel’s radius and length of the blood vessel. Moreover, as the magnetic strength and size of the magnetic particles increase, the accumulation of nano-particles increases, as well. It is also found that the effect of doubling the magnetic field from 4 to 8 tesla increases the pressure drop by nearly 15%, but it shows marginal influence on the wall shear stress.
