5-gauss line

The boundary around an MRI magnet where fringe field drops below 5 Gauss. Ferromagnetic objects within the line are at risk of becoming projectiles.

Why it matters to buyers: Siting requirement — establishes room layout constraints. Typically 8–12 feet from magnet center on 1.5 T.

Why it matters to engineers: Survey magnet fringe field during siting; post the boundary with physical markers and signage.
