A number of experimental and clinical studies have established that an alternating magnetic field affects hemodynamics, generally by an improvement in blood circulation. In a paper published in the Russian journal Biofizika, an investigator hypothesized that this effect, at least in part, can be explained by movements of ions in blood induced by Lorentz forces; these movements increasing pressure from inside blood vessels, leading to vasodilatation. A mathematical model was developed to evaluate the vasodilating effect quantitatively in various types of vessels. [BENER 12446]

After working at a defective computer monitor where the text was `jumping', I experienced a sub-conjunctival haemorrhage in my left eye. This event occurred many hours after I'd stopped using the monitor and on examination by a medical practitioner, was considered to be related to coughing fits which I'd suffered from in the preceding month. Is this mere coincidence or evidence for a connection between vasal dilation and unusual EMF activity (for a VDU, that is)?
