How to calculate magnetic power that attract iron in blood?5 answersThe magnetic power that attracts iron in blood can be calculated by measuring the magnetic susceptibility of the blood cells. Magnetic susceptibility is a property that quantifies how easily a material can be magnetized in the presence of an external magnetic field. In the context of blood, the magnetic susceptibility of the cells is primarily influenced by the presence of haemozoin, a byproduct of the degradation of hemoglobin by malaria parasites. The magnetic susceptibility of haemozoin has been measured to be (11.0+/-0.9)x10(-3) mL mol(-1). By quantifying the magnetic susceptibility of the blood cells, it is possible to determine the magnetic power that attracts iron in blood.
