Static Magnetic Field is a field or area caused by the movement of electric current. Measurement and control of static magnetic fields are carried out in workplaces that have a static magnetic field hazard source.

Under certain conditions, sources of static magnetic fields can present health hazards. Factors affecting potential hazards include:

1. Magnetic flux intensity associated with the source
2. Design of the magnetic field source
3. Accessibility of the magnetic field
4. Equipment/hazardous materials associated with the magnetic field source

Sources of large static magnetic fields may require appropriate controls to mitigate potential hazards. For sources intended to produce human exposure to the magnetic field (such as MRI devices), it is critical that safety precautions cover not only the user of the device but also the research subject.
