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:

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
