Static Magnetic Field Limits
|General Public:||Upper Limit (T)|
For shielded magnets, the 0.2 T line corresponds to the entrance of the magnet bore, therefore it should not be difficult to remain well clear of this field strength. Ensuring that no member of the general public is exposed to more than 0.5 mT means that no member of the general public should enter the Controlled Area.
