Abstract
Electromagnetic devices such as superconducting magnets, magnetically levitated vehicles and magnetic resonance imaging (MRI) create high magnetic fields within their immediate vicinity. This has generated some concerns over the effects that these fields may have on the outside environment and in particular on living organisms. 50/60Hz magnetic fields are of special concern because living organisms are exposed to them on our environment. The measurement of low frequency magnetic field on our environment is important to find out a possible relationship between magnetic field and health hazards. The low frequency magnetic field measurements in urban locations are presented. We investigated the influence of a strong 60Hz AC magnetic field of about 1.0T on organisms. The high AC magnetic field is generated by using a multilayer eddy-current type AC magnetic generator developed in our laboratory. In this paper, the generation of heat shock protein by magnetic stimulus is discussed in nematode, and in vitro experiments were performed with biochemical reactions, enzyme and DNA synthesis.
