A US Food and Drug Administration study of devices such as MagSafe and the iPhone 12 found that the risk to patients with pacemakers is low, but caution is advised.
After Apple reworded its support documents for the iPhone 12 and MagSafe to recommend cautious use of the devices near pacemakers, the FDA issued its own guidance. The FDA has conducted its own testing and says that while caution is warranted, the risk of problems is low. Jeff Shuren, MD, JD, director of the FDA Center for Devices and Radiological Health, explained in a statement:
We believe the risk to patients is low. The agency is not currently aware of any adverse events related to this issue. However, the number of consumer electronics containing strong magnets is expected to increase over time, so we recommend that people with implanted medical devices speak with their healthcare provider to ensure they understand this potential risk and the proper techniques for safe use.
It's not just the iPhone 12 and MagSafe that are meant
Potential issues with magnets in devices like Apple's were first raised in the Heart Rhythm Society's Journal in January 2021. Apple had advised users to consult a doctor if they were unsure whether the magnets could interfere, but then updated that to provide more detailed guidance. Specifically, Apple advises iPhone 12 users who have pacemakers or use similar medical devices to keep the phone between 6 and 12 inches away from such devices. The FDA's separate testing has resulted in similar advice.
It is important to emphasize that to avoid interference between cell phones and smart watches and your heart device, keep them at least 15 centimeters (6 inches) away from implanted medical devices. Also, do not place cell phones, smart watches, and other consumer electronics near your implanted medical device.
Although the FDA focused on cell phones and smartwatches, its reference to the increasing use of magnets is not limited to that product category. In addition to magnets in various iPad models, Apple has separately been researching expanded use of magnets in case covers and wearable Apple Watch bands. (Photo by hadrian / Bigstockphoto)
