MRI magnets are always on? Huh, learn something new every day. Some days more than one thing.

There were likely more than 2 signs that warned him not to bring metal near the machine.

They're always on. The only way to de-magnetize the superconducting magnets is to dump the liquid helium that keeps them cooled to the level of superconductivity. This destroys the superconductor, and can quickly suffocate anyone in an older MRI suite if you don't get out fast.

Pushing that big, red "emergency" button to do it is about a million dollars a pop.

So, a service gun worth a few hundred dollars stuck in a MRI, IS like a nickel holding up $1,000 dollars.

He's lucky there wasn't anybody between the gun and the magnet or they would have been injured or worse.  IIRC a couple of people have been killed by stools and chairs flying through the air and someone was injured after he brought a floor buffer in and it caused hundreds of thousands of dollars in damage to the machine.

Wouldn't be surprised if that thing ripped off his gunbelt and took the top half of his pants with it. Those babies are not toys, they can seriously fark up your day if you have a paperclip on you much less a few pounds of gun, pepper spray canisters, extra magazines etc..

Pretty sure the old ones are too. The need liquid helium to stay cold enough. Seems like they could use the high temperature variety. Anyway, they're always on because it basically a superconducting wire in a loop. Send a large current into the loop and it'll just keep going round and round making a powerful magnetic field. Seems like something could be placed near the MRI to induct all the current away.

In unrelated news, the Hadron SuperCollider has just trolled the NRA claiming that bullets travelling much less than the speed of light are lame, but way too expensive, and that Wayne LaPierre is a submoronic particle.

believe it or not these hearty magnuts are not just out in the open without a dazzling amount of warning decals and such to make it as safe as possible. one typically has to access a few locked doors to find the prize.

i've wondered if companies/businesses give ahead of time warning to first responders regarding industrial dangers, and if they supplied building blueprints.

They're heavily shielded because any induction loss makes the magnetic field lose strength and starts adding interference into the image from the noise it produces (iirc) and the shielding also helps focus the strength of the magnetic field towards the patient and away from pulling down everything in the building around it. A lot of the older ones are either actual solid metal magnets (fancy niobium alloys i think) or they use traditional electromagnetic induction coils that need constant current input to function but they're not used much anymore as they can't even come close to the resolution or power of the superconducting magnets. I don't know how common those are anymore (never worked on them).

I'd blame that on media scare mongering about plastic glocks that can slip through metal detectors.

/Much of the reason there is even debate about things like the AWB is because of rampant and willfully ignorance shoveled from reporters mouths to the publics ears.
/Most people don't go back to double check what they hear, so a little bad info can carry far.

Stainless steel should be fine also.  I am pretty sure only regular steel, iron and alloys will cause any trouble.  Any scrapper knows real stainless steel from fake stainless steel by magnate.

Less metal means that it was less likely to have been magnetically wrenched away from him, but as there are a bunch of glocks on patrol: I wouldn't bet it wasn't a glock. I have noticed that I see a lot less glocks on patrol than I used to see. A lot of them are similar to Glocks in that they have composite frames and parts, but I think more and more people don't like the safety mechanism (some really do). I think in the end it's a wash. It could easily be a Glock, but I don't think that just because we want it to be a Glock to prove some to some idiot that a Glock could be magnetically attracted to something makes it more likely.

/Meh.

Because there is no way to turn off the magnetism, the gun remained in place and no one was shot? inside the building.

Actually, there are different grades of stainless steel.  Some of them are magnetic.  Others aren't.  I've got a harmonica with stainless steel reeds that's been set up with magnets so you push a button on the side and the magnets move closer to the reeds, and the field changes their pitch.  The same technology doesn't work on brass reeds (unless you solder something magnetic on them.)
