Impact of magnetic field on biological function and suppression technique

Due to the ever increasing amount of modern equipment, electromagnetic pollution is increasing in a complex manner. In this pollution dominating world the entire human society is living in an electromagnetic environment. The effect of radiation on human beings is now playing a vital role, which may sometimes become fatal. The users and other inhabitants of the vast computer community and others where the chances of the electromagnetic environment existing, have become aware that serious questions are being raised about the potential harmful effects of the electromagnetic emission from display monitors and other such equipment. The magnetic field at ELF, VLF and non-ionizing radiation may cause biological effects and finally may lead to pressure, ulcer, high blood pressure, coronary heart problems and cancer. For magnetic field lines of force that readily penetrate almost anything including the human body, the existence of such a field can be visualized by proper EMC measurements. This paper is a study of the magnetic field produced by visual display units and the preventive measures to minimize the ill-effects.
