Must have been a pretty sturdy chain!
The schedulers even tell you no jewelry even though silver & gold aren't magnetic.
I had to get my wedding ring cut off & resized because chronic tendinitis wouldn't let me get if off. And, it's 18k gold.
I was at CERN about 25 years ago and they only use aluminum & brass tools. Even on stuff that is 10 meters from the magnets.

Humans are often very careless about serious matters.
Good thing Karoline Leavitt ditched her cross and chain.😀

Crazy

I do wonder where the tech was.
I just had 6 scans done in June (or maybe May). The tech was in the little control room the whole time, and the room mic was on because she would talk to me & could hear me reply.
Pretty unusual set of circumstances.

They usually guard the MRI room very carefully because of the dire consequences of something going wrong. It sounded like the guy's wife asked the attendant to get her husband for assistance, got no response, so the guy responded.

My daughter has a scan every year - and occasionally I have been allowed in with her. They have had quite the routine to make sure that not only does she not have any metal, neither did I. Aside from the human cost, it can cost $50,000 or more to shut the thing down, which they have to do to release anything which attaches itself to the machine (like a heavy chain, a metal wheelchair, etc.) And it may have to be off for a few days.

chain of events.

Nice play in words

I consulted ChatGPT (yeah, I know) and asked it to calculate the force a 2 Tesla magnet (which IIRC is in the range of an MRI magnetic field strength) on an iron mass of 1 lb. At a 3 foot distance, it calculated a force of little less than 1 lb. At a 1 foot distance, the calculated force was about 30 lbs. So, this wasn't a case of the guy walking in to the MRI room and getting sucked right in - he must have gotten very close and probably would have had ample warning of what was about to happen if he got any closer.

BTW, the analysis presented by ChatGPT was detailed and IMO very impressive. I'd copy it here but the formatting gets screwed up.

I once had an MRI and I couldn't get a small iron ring off my finger - the tech said don't worry about it and I noticed no effect on the ring at all.

Never had an MRI

happened to me years ago. Was having my neck scanned in one of those tube things. They told me 3-4 times make sure all metal and jewelry is removed etc. They shoved me inside the thing and it started clicking and then it occurred to me I had my wedding band still on. I panicked and started hollering at the speaker and told them what was up and they were like, yea no biggie don't worry about it.
I'm guessing that inside the machine maybe the fields aren't that high? I don't know, just thought it was odd that they made such a big deal about it then told me it wasn't a concern.

The field strength inside the tube must be high for the thing to work as your bod is inside the tube. I expect your wedding ring was not magnetic material such as iron, cobalt or nickel but still.....

machine was running - no one stopped him. Clearly he was clueless in this matter. That poor widow.

I've had several MRIs and have never had to take off my 3 rings, which would not come off if someone tried
