Abstract

Interest in the biological effects of magnetic fields is increasing with the widespread use of magnetism in such devices as synchrotrons, fusion reactors, magnetically levitated trains, and medical equipments. However, the biological effects of magnetism have not yet been well explained. In this paper, the whole-body exposure to large magnetic field is distinguished from the local exposure to small magnets. Similarly, in considering biological effects, systemic and local responses are distinguished. Systemic biological effects were noted after long-term whole-body exposures, but it was difficult to verify the existence of biological effects after short-term exposures even at high doses. The effects of magnetism on animals appear to be weak; it initially acts as a stimulant, and later as a depressant. These findings may have medical applications, and in any case, they certainly indicate the need for continuing hygienic studies.
