Ferromagnetic detection systems have been used to prevent accidents related to external ferromagnetic objects (e.g., pocket knives, hearing aids, and so on). If a ferromagnetic implant was missed during MRI screening, the ability to use a ferromagnetic detection system to discover the object in a pa...
