Off topic but Oxygen is not a metal. The solid and liquid forms are strongly paramagnetic, but it is on the wrong side of the periodic table to be a metal.

GT, I just have to ask what your background is. You are, I believe, the only person I have ever encountered that is aware that oxygen is indeed a metal. (Not that it comes up all that often in conversation)

I'm an engineer. However, I don't believe oxygen is a metal --- it doesn't experience metallic bonding (disassociation of electrons) but it exhibits some magnetic properties when in the unusual liquid state. Sometimes, "looks like a duck, quacks like a duck" results in something that's not a duck.

You're not supposed to have any metal objects on you when you enter an MRI room including zippers, pens, pins, etc., and certainly not a firearm of any type. That means in the room itself, not just in the MRI cavity. There was an incident where an orderly wheeled in an oxygen cylinder when a young boy was having an MRI, the cylinder was rapidly accelerated toward the cavity and the boy was killed by it. A similar incident occurred at a different facility, but the MRI attendant and the orderly were able to wrestle the tank out of the room before any damage was done. Most often the damage is done to the MRI machine itself by heavy metal objects, not the humans in or around it.

that very well may be. however, if you watch the show, the doc has a clipboard, metal pen, pin on nametag, purse strap latches, buttons, zipper, etc etc etc yet only the gun is magnetized

I didn't see the show, was the doc in the machine room when it was activated, or was he in an observation room?

um in all my years on this planet i have never seen a non ferious materal IE: LEAD become magnitized and last i checked there were only a verry few rounds made with steel cores so my bs meter just peged.
as for the extasy in the paint im not a chemist but i dont think its possable to retrive the drug after its in an emulsion such as paint. again im no chemist therefore im not a expert on the mater but i still dont beleve it to be possable.

I contend you are wrong.
Any metal , ferrous or non ferrous when in a magnetic field becomes magnetic. Just ferrous metals retain their magnetism when the field collapses.
I used to work in a copper leach plant where high current at low voltage was passed through big copper bus bars to extract copper by electroplating.
The copper bars were so magnetic that they would pull on your wristwatch and pull your hand against them New guys always though they were going to be electrocuted and would scream as they were dragged against the buss bars. Needless to say the wristwatches never worked again Even other copper components , when in the presence of the strong magnetic field of the bussbar would attract to one another and cling together and jump to the bussbar.
A lot of ammo have STEEL copper plated jackets and those would remain magnetized .

The magnetic field is always on since the current circulating in the field coils see no resistance because they are cooled close to absolute zero thus exhibiting superconductivity or zero resistance. The magnet does not require any outside power to stay up just coolant. If you lose that the whole thing runs away (called a quench) the coils heat up because of I squared R losses boiling off more liquid Helium until the helium is gone and the field shuts down. So the current in the coil just goes round and around ad infinitum until you loose cooling.
