Strong magnets hold the MagSafe charger to the back of an iPhone 12
But that doesn’t mean that everyone is home free. The FDA is concerned that the number of consumer devices containing strong, powerful magnets is expected to increase over time, and recommends that those with an implanted medical device discuss the situation with their health care provider. Dr. Shuren says that the agency “will continue to monitor the effects of consumer electronics on the safe operation of implanted medical devices.”
The FDA also had some tips to prevent situations when a strong field magnet placed in a consumer device goes into “magnet mode,” which can affect the normal operations of medical devices. The agency suggests that those with consumer gear like smartphones and smartwatches keep their devices at least six inches away from the medical equipment implanted in their bodies. In addition, the FDA also says that consumer electronics should not be kept in a pocket placed over the implanted medical equipment.
