The interaction between static magnetic field(SMF) and biology is a rapidly-developing research area. As a physical factor, static magnetic field is non-invasive and can act on the organism directly. However, its effects are two-fold,with both potential therapeutic effects and pernicious effects, and its mechanism remains to be studied and elucidated. This paper discusses the biological effects of static magnetic fields from the four aspects-the effects of static magnetic field on oxidative stress, biological cells, human body function and its inhibition to tumor cells, with an aim to improve ...
