iPhone and Apple Watch magnets are strong enough to disrupt pacemakers

Researchers warn that Apple's iPhone 12 or Apple Watch 6 could cause damage to medical implants like pacemakers, if they are too close to the body.

These implants are often equipped with a magnet mode that can be used to deliberately trigger a strong magnet during a procedure that could cause interference, such as an MRI scan.

While internal defibrillators will not deliver lifesaving shocks in magnet mode, pacemakers will continue to drive the heart at a constant pace.
