Not sure what they thought they could do. The only way to demagnetize an MRI is to either ramp down the current driving the magnet, or dump the helium. Until the field is down, you’re not pulling anything off that monster.

Indianapolis: Gun discharges in 'procedure room' at Indianapolis Veterans Affairs hospital
“some anomaly will cause a small domain in the magnet to decide that it’s tired of the superconducting lifestyle (I am bypassing the more technical explanation).”

Bring a gun to a hospital? What the hell. It’s a security blanket, isn’t it?

Do you know if going at the problem with a mu-metal shim or a superconductive shim placed warm and then cooled until the Meissner effect kicks in would let you remove the gun without powering down the magnet; or is the field strength sufficient that comparatively lightweight tricks aren’t going to cut it?
Shimming absolutely wouldn’t do the finish of either the MRI or the gun any good; but I suspect that you could get a shim in there; I’m just not sure whether you could get the necessary magnetic field attenuation/redirection from a shim small enough to get in place.

What a dumb way to die.
MRI magnets are no joke. I’ve spent several hours of my life in side of them.

So then you’re probably well qualified to explain to the Juggalos how magnets work

I sympathize. I have to get hours-long MRIs every six months. Brain and spine, with and without contrast.

The solution here is clear. We need to arm MRI technicians.
/s of course, but you can’t be too careful these days

Gun nuts never seem to get that guns have a nasty way of being taken away and turned on the owner.

No, it was still the gun. The MRI just aimed it…

If this happened to someone vilified by White Christian Nationalists, they would say it was God’s work.

Somewhat related nostalgia: …was witness to a trash-bin slowly move then fly across the room to stick to a NMR (magnetic resonance) machine, which are related at least in magnetic strength to MRI machines. This after the janitor was told he couldn’t clean-up in that room as the trash-bin had a metal dolly; and which subsequently “quenched the magnet”: a whole lotta helium gas suddenly exhausts. Serious magnetic fields are not to be taken lightly.

Never bring a gun to an MRI fight.

I’d think so; they’d have to stop laughing and get to work!

More complete reports published in the São Paulo press say that Mr. Novaes was duly informed about restrictions on metallic objects in the room. He read the instructions and signed a document that stated He wasn’t carrying anything metallic. Newspapers stated that he even kept two clips of bullets in a locker in another room, but somehow kept the gun with him. Perhaps afraid of handing a lethal piece of equipment to an unprepared person or leaving this deadly tool unattended, he decided to keep the 9 mm gun with a bullet.
He was accompanying his mother, who was supposed to be examined with the aid of an MRI machine. The newspapers didn’t even try to speculate what the lady’s health problem was, but it seems that she was nervous going into that “tunnel” and Mr. Novaes decided to enter the room to comfort her.
He was a weapons enthusiast and as a lawyer he defended the right of Brazilian citizens to have a weapon or small arsenal for self-defense.

Magnets, how do they work?

They resonate, umm… imagerily.

Different devices and technologies. MRI is used more often than NMR.
