In short, it’s basically a hybrid.

From the point of view of a body experiencing it, it’s just an extreme tidal force (which is not actually a force, but the rate of change of acceleration induced by some force with respect to position). It is space time being stretched, and that would produce tension on an object falling into a black hole (and I think there’s also compression in directions perpendicular to that tension, as depicted in the image you shared, but I don’t recall the details off the top of my head). Early on, that tension is not sufficient to break apart molecular bonds, but eventually it is, and the object will indeed get ripped apart. Eventually that tidal force might be strong enough that molecules get ripped apart, and at some point the curvature could be enough that you have to modify the very description of fundamental particles, at which point you’re getting into questions of quantum gravity, which are beyond the scope of experiment at present, and for which there are no generally accepted theories.

I feel like the ripping of molecules would happen due to the magnetic field way before gravity has a chance to do so. And also gravity would first cause the ripping of the physical structure across the weak points ( joints and such? idk too much about anatomy).

There isn’t necessarily any magnetic field. Spaghettification happens even in an idealized non-rotating, charge-neutral black hole.

> ripping of the physical structure across the weak points

Those points are bonded together by some kind of chemical bond, like hydrogen bonds between different atoms.

so the human body cannot snap in half if pulled apart with huge amounts of force?
