Wow. Nice sift.

What happens when those 2x4s snap like a toothpick?

Wow, what a GREAT use of medical equipment!

I thought it said stripper.

So, this is a decommissioned MRI, and they have a blog all about things to do with MRIs and safety. There are other videos of the same ilk which are obviously aimed for display at the hospitals themselves.

MRIs are very dangerous, and people don't necessarily know that, being that it's an 'invisible' danger.

What if i put my balls in there?

Comment hidden because you are ignoring dag.(show it anyway)

Depends. Do you have balls of steel?>> ^mxxcon:

Not steel but wolfram..

MRIs aren't exactly roaming the wild. The only time you would be in close contact with one if you're not in the medical field is if you're in a very skimpy gown. I don't really think they're all that dangerous if you can't really play with them or anything.

@Yogi yeah, the idea of safety here is for the staff. People who work at the hospital need to know the power of these things.

That makes sense to me because I was one of the kids who actually got scared watching those instructional videos at school.

I have always wondered about various metallic objects and MRI machines. But the two times I have ever been in close contact with them, the the jerk nurses made me remove all metal.

But now I know it's because they knew I would have too much fun.

Put two MRI machines next to each other! (you might want to stand back)

I think you'd be surprised at what a few boards can handle...>> ^bmacs27:

I put a big aluminum bar directly in one once, and got to move it around... its weird. Even aluminum responds.

Not in the same way as iron, though. Aluminum is not ferromagnetic, and is therefore not attracted to the MRI magnet. But if you move it around in the magnetic field you will induce an electrical current in the aluminum. This electrical current sets up its own small magnetic field, and it's this new field's interaction with the field from the MRI that you can feel when you move the bar around. The interaction stops as soon as you hold the bar still again.

Oh, and this is a 4 tesla magnet. In my field of research, I work with magnetic fields up to 14 tesla. But not on such a big scale as here.

Nice one orn... Also, i'm really not happy with the level of safety involved here.

There are research magnets as well. I know guys that mess around with them all the time. At my old school, they had just gotten the new research magnet, and fired it up. Someone must have been really concerned about safety when they built the building because for some reason they decided to put a fire extinguisher in the room. Whoops.

So imagine if the patient neglected to remove a tongue piercing or worse yet - Nipple or genital piercings...

And yet another reason why i dont get magnets .. I just dont understand them...

Thanks! interesting.

This is exactly why they always ask you a lot of questions before they put you in one of these machines, for instance about whether you have a pacemaker, or whether you work with metal regularly. Just a tiny grain of metal dust can really wreak havoc with your body if it's logded in some critical place such as, say, your eye.

Awesome reply. Your science embiggens my mind.

Fucking magnets how do they work?!

"Quick, what does the scale say about its magnetic pull?!"
"It's over 9000!!!!"

I'd hate to see what happens to people who have some unknowingly magnetic alien element in their head from an abduction. Oh, that's right alien abductions aren't real. DAMMIT! If only there was a god...

But this pales in comparison to the power of the dark side!

so what happens if you have braces or a metal plate in your arm? that would be awesome if it got ripped off!
