> This stuff gets measured all the time, also for equipment that is to be used in aerospace and hospitals... They only measure dynamic magnetic fields (i.e. electromagnetic fields). There are essentially no regulatory limits in static fields, since they don't really interfere with RF signals. In fact, is amazingly easy to purchase neodymium magnets of a size that should not be that easily available, which explains the hilarious safety videos like this one[1] [1] https://www.youtube.com/watch?v=0t8yDnyOaQ8 https://www.youtube.com/watch?v=0t8yDnyOaQ8

Now that I read that, it seems obvious that static fields and RF wouldn't interact like that... Thanks! The video is very well done (for a semi-pro it seems?), it's one of those things where people (including me) might think "oh yeah magnets, I know about those" but you actually don't, or at last not at the scale that you might need. That reminds me of this LPL video about Gallium: https://www.youtube.com/watch?v=jeghGhVdt9s https://www.youtube.com/watch?v=jeghGhVdt9s where you might think: oh yeah, metals, those are sturdy blocks that you need to weld or saw.
