My bullshit alarm is going off. MRI machines use very powerful magnets for imaging: usually around 1.5 Teslas, but some go up to 10 T, and there are concepts for machines up to 14 T. That is a billion times stronger than a 500 nanotesla fluctuation. And MRIs are completely safe. If a 500 nanotesla fluctuation was a cellular stressor, I could only imagine that a 10 T MRI would cause very obvious damage.










blessed.rs is my usual place to get started with these sorts of questions, and they have a section on cryptography crates.
