Yeah I want to see them try that on a 7T

Oh god the axe head would probably weld itself to something with the amount of force it would hit. Are 7Ts used in mainstream medical imaging yet? My dad is an MRI tech and just got a new 3T at his hospital.

Yes! But only the big ones. Mayo Clinic is the only one I know of that got one in 2017

I think that '7T' refers to 7 Teslas. I think (note that I am an engineer and not really involved in the response to the fires) that the main determining factor to if they can pull the ax off of the magnet is how close the ax got to the magnet. The force of the pull of the magnet is inverse (or inverse squared) to the distance so if the ax gets really close to the magnet then it is basically impossible.
