  • Why are you spounting this half-coherent nonesense?

    magnets are always on

    No, MRIs use electro magnets which can be turned off. But they are on most of the time

    so person would be pulled as approach not suddenly ripped out in machine

    Yes the metal would be pulled towards the machine as they approach, but the magnetic force quickly becomes much stronger inside the machine

    magnets are just not that strong

    There are different magnets of different strengths, and scientists in labs are constantly pushing the limits, trying to make stronger ones. And the ones in MRIs are really freaking strong, that's why these machines are so expensive

    or people with like metal filings in skin would be turned into bloody mess. We're talking all machinists here

    Yes machinists are at risk, metal workers are specifically mentioned on this website:

    https://www.radiologyinfo.org/en/info/safety-mr#fff2f44ba7624ad1a1ac3b91ab12b599

    Items that may create a health hazard or other problem during an MRI include:
    A metallic foreign body located within or near the eye (such an object generally can be seen on an x-ray; metal workers are most likely to have this problem)

    No they are not blended to a pulp, but yes they can be injured

    not really possible to make magnets that strong for a number of reasons

    What reasons? MRIs use superconductors cooled with liquid helium to overcome electric resistance

    magnetic field is in the tube, which is why it works. Shit pulled towards middle

    ? Yes MRIs do infact work
