Figure 1 Warning sign
Magnetic Attraction Zone
The “magnetic attraction zone” is established to prevent
ferromagnetic objects from becoming projectiles; it is usually
confined to the room that houses the magnet. The magnetic
attraction zone threshold is usually at a magnetic field
strength of 30 gauss.
Occupational exposure to magnetic fields
Consult national and state enforcement and advisory bodies
to ensure that any exposure limits are not infringed for
(nonpatient) occupational workers.
At magnetic field strengths of approximately ten gauss or more, magnetic
media can become wiped or damaged.
Do not allow ferromagnetic objects inside the Magnetic Attraction
Zone.
