Can the RFID chip found inside the Prius transponder keys be damaged due to close proximity to an N52 magnet? I am talking about the small capsule used to disable the ignition interlock computer and allow the Prius to start. I read about RFID chips in general and saw that they apparently can only be destroyed due to physical destruction, high voltage, or microwaves, but I wanted to make sure they are invulnerable to very close proximity (less than a mm) to powerful magnets, like N52.
The chip was accidentally exposed to an N52 magnet for a few seconds, but it still works. Based on that and my reading, I suspect the chip cannot be damaged in such a manner. Additional technical experience is welcome.
If you had a non-magnetic material ring, say aluminum, and passing the hand over the magnet fast enough to feel some heat, there might be a risk. If you'll provide the magnetic field strength, Maxwells equations can calculate the expected induced voltage and current. But back of the envelope, you'd probably have to us a sling-shot or air-gun to move it through the magnetic field enough to even slightly risk harm. Go with confidence and watch what you have in your pockets. Bob Wilson
