Abstract
The increasing potential for exposure to magnetic fields in science, industry and public sectors requires an assessment of the attendant potential biological consequences. At present, no model exists for such an assessment. Based on the physical principle of pressure loss when a conductive fluid moves through a magnetic field, a model of the cardiovascular system is used to estimate the potential increase in blood pressure in the presence of a magnetic field. This increased pressure, confined to the major arteries, along with epidemiological data, is used to provide the basis of a model which could be applied to make upper limit estimates of risk for blood pressure related health effects resulting from exposure to magnetic fields.
