I was asked a question today which may not be exactly electrical in nature but here goes.
The parking meter guy has had problems with the electronics in the parking meters going bad. I believe they run on batteries (no power supply from an external source.) About a year ago an MRI office opened across the street from the meters and since then the problems have been occuring. (No problems before this to my understanding.) Is it possible that magnetic fields from the MRI machines are causing problems with the electronics of the meters?
The distance is a typical two-way street, a sidewalk and whatever the distance inside the building the machine is. I'd say roughly 50 to 75 feet.
I haven't done any real investigation, I was just posed the question today.
