MRI's in all the schools, stat!

Good thing he didn't have any plates or screws for various body repairs.

What -- no crystal skull references?

I am disappoint.

From the comments:
"Put one of these machines in each of our schools. Problem solved."

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

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

Some people think they do not need to follow the rules other people follow.

So, what you're saying is "gun free zones" don't work...

I always thought they were elctro magents that were only magnetic when they turned on the power.

I'll be impressed when it finds Sarah Connor

Giltric: I always thought they were elctro magents that were only magnetic when they turned on the power.

Some are some aren't, depends on how they're made.

The newer ones are superconducting electromagnets... super sweet

Well, it is a cop in TFA.

How much you want to bet it was a glock?

People seem to think that combat tupperware doesn't have metal in it, for some reason.

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..

Can't get more evil that that.

Trapper-Keeper MRI Apocalypse

-On SyFy this March-

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.

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.

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 thought machines had been arming themselves for years...

A similar incident happened in Western NY 11 years ago... But that bozo cop's gun actually went off (!)
