Effects of static fields

Static magnetic fields exert forces on magnetisable metals as well as on moving electrically charged particles. As an example humans use strong magnetic fields for medical imaging methods. To date, investigations have not revealed any direct negative biological or health effects from static magnetic fields with magnetic flux densities of up to four teslas. Further research is needed on the effects of stronger static magnetic fields.

WHO risk assessment

In 2002 the International Agency for Research on Cancer (IARC) which is associated with the World Health Organization (WHO) classified low frequency fields as class 2B "possibly carcinogenic". The crucial factor for this decision were the epidemiological observations of a statistical association of childhood leukaemia and an exposure of the children to magnetic fields in the range of more than 0.3 to 0.4 microtesla (µT), averaged over time.
