My uncle is a medical equipment installer that installs and calibrates MRI machines.
The issue is more than just the physical damage, which can be expensive, these machines take a long time to calibrate to the local environment. If the electromagnets are damaged, the whole set needs to be replaced, as they are manufactured in matching batches.
It's like if you damage a piston in an engine, it will cause damage to the crank shaft, which will also damage the rest of the engine. It's a helluva job to fix.
I don’t suppose your uncle knows what happens to those magnets that come out…?
You know. Asking for a “friend”. (Okay so this hypothetical friend maybe likes to play with magnets in a totally harmless way….)(edit, yes I know how dangerous they are…. I’ll make sure my “friend” is careful….)
The primary magnets will be super conducting magnets. Unless you have liquid helium (or liquid nitrogen, if your lucky) to cool it, it will just be an interesting rock.
There’s a facility a few miles from me that makes the LN. used to work at a facility that had a tank farm served by them. Their driver liked to smoke while purging the liquid hydrogen tanks.
And not like, walked over to the smoke shack, nope. right there next to the exhaust vent.
🤣
Just make sure to tell your friend that 600amp wires are expensive and THICK.
Promises promises….
