In this case, I mean a static (but strong) magnetic field. I'm aware of Faraday induction, and have seen some electronics damaged by it when carried close to a powerful magnet. But does a strong static field disturb electronic components? I recently saw a new MRI scanner with a 3 Tesla magnet. One of the new features was a redesign of the RF receiver. Previously, the antenna array (which goes into the main field of the scanner) was connected via coax cables to a receiver outside of the main field. This new scanner integrates the RF receiver and digital processing module into the antenna array - boasting improved SNR due to removal of the relatively lossy coax. The same scanner also comes with EKG monitoring. Normally, this would be done by a conventional monitor placed away from the magnet. This scanner, however, comes with a wireless monitor that goes on the chest, and communicates with a wireless receiver placed elsewhere in the room. So, is a static field disruptive at all? What about if the electronics contain magnetic components - e.g. inductors/transformers? Is there a way to avoid magnetic saturation of such components when exposed to the field?
