MRI experience
Hey y'all,
I had an MRI done today and wanted to share my experience. The MRI scan was of my knee and my magnet is in my left hand's pinky finger. We think it's an N42 based on my last post:

Anyway, the experience:
- I wrapped my finger in scotch tape pre-emptively (although pretty sure it did nothing)
- Magnet started flipping like crazy as I approached the machine (similar to MacBook Pro laptop speakers, hate those)
- I'd estimate about 5 feet from the machine, it started flipping
- Talked to the tech about it, she said it was a 3T machine and suggested I could use a lower strength machine but I insisted on doing it
- Machine was branded as a GE (didn't get a model number =/)
- Lied down in machine, held finger up on chest (it got close to but never entered machine, scan was only for knee)
- They gave me a trigger to squeeze in case anything went wrong
- During the scans, the magnet didn't seem to vibrate/move at all
- Magnet flipped a bunch again as I got up and walked away from machine
- MRI scans look like they came out clear with no interference from the magnet (will be seeing the doctor next week)
- Magnet feels fine and reacting as per normal

I'm guessing I felt the superconducting magnet as I approached but the coils (i.e. what make the images possible) generate fields that are contained within the machine (i.e. nowhere near my finger which was out of the machine)
