How An MRI Machine Zapped Only Apple iPhones, iPads And Watches In An Entire Building
Redditor u/harritco remarked that he had experienced the “most bizarre issue I've had in my career in IT”. A medical facility had installed a new MRI machine and by the end of the day every iPad, iPhone, and
Why would an MRI machine only affect iOS devices? Redditor u/harritco called General Electric (GE) and they believe that a helium leak was the cause for the incident. Redditors u/captaincool and u/luckyluke193
Most modern devices incorporate microelectromechanical system (MEMS) oscillators. MEMS oscillators resonate frequencies that can be used for a variety of tasks such as measuring time. These resonators are placed in hermetically sealed chambers in devices, because they can easily be affected by small atomic gasses like helium. Unfortunately, the sealed chambers are not perfect and can be rather cheaply made allowing Helium at higher atmospheric concentrations to leak through the seal and increase the pressure in the chamber. The redditors theorized that most iOS devices probably share similar MEMS oscillators to reduce costs.
Why were the Android devices not affected? The devices likely have different MEMS oscillators made with different specifications. The moral of the story seems to be do not bring an iOS device to a MRI fight.
