It is critical for personnel with cardiac implants or ferromagnetic metallic implants to understand hazards associated with magnetic fields before beginning work with magnetic field producing equipment. Strong magnetic fields have been documented as having the capability to interfere with these personal medical devices.
Magnetic field production poses an additional risk of injury to all lab personnel if the field produced is forceful enough to create projectiles through the attraction between ferrous items and the magnet.
When working with this type of equipment, users should also keep aware to prevent damage to magnetic media such as ID cards, cellular devices, and hard drives.
