Understanding Pacemakers and Their Impact on Daily Activities

4. Magnets and Pacemakers

Magnets can also disrupt the proper function of a pacemaker if they come within six inches of the implanted device. Common magnets for home and office use pose only a small risk, but magnets made from neodymium-iron-boron can interfere with cardiac devices. Some of these stronger magnets may be in jewelry, toys, and clothing. Therefore, people with pacemakers should always read the package warnings for purchased goods. However, all manufacturers are not required to put magnet warnings on labels.
