Carry an MRI machine around with you to protect yourself from armed robbers. Need one in every quick stop, bank, etc. to stop armed robberies.
A lot of east bloc dentistry used to use ferric metals. I wonder if they still ask about dental work before an MRI.
Lucky no one was using the machine. At one of our local hospitals a few years ago someone walked into the MRI room with a metal coffee cup. The patient laying on the bed died. What a sad way to go!
You’re going to have to ramp it down and hope that you don’t quench it. Typically you can ramp it down to .2T and get a come-along type of ratchet strap to get it past the 1 Gauss line. then you can remove it from the room.
Perhaps the officer had seen Die Hard 2 and believed his Glock was porcelain.
There was probably a sign on the door, no metal inside this room. Which cops probably ignore because they’re so used to thinking the rules don’t apply to them. Well, MRI machines are perhaps real gun-free zones.
Only in Chicago would a burglary lead to an MRI machine.
MRI machines have a powerful static field. It’s created using a coil cooled by liquified gas... the low temp means the current just keeps circling without resistance. Start it up and it sort of just keeps going.
The strength is around 4 Tesla if I remember correctly. You can create a field this large at home if you charge a bank of high voltage capacitors and discharge them into a small coil with just a few turns. The coil is best made with a heavy gauge silver/copper wire...this stuff is amazingly stiff and hard to wind though.
Your enormous magnetic pulse will last only a microsecond or so and the discharge current is enough to power a small city (for a microsecond anyway)
You can crush cans with such a device...that’s the trick geeks love to perform.
