    Really, what you need to do is find a simulator that will answer these questions, or, for the simplest geometries, solve the equations yourself.

    How would i find those simulators?

    And how would i use them to solve this question?

    The mathematical singularity where GR fails us, involves infinite spacetime curvature and infinite density, and this is why cosmologists do not believe it exists. Although we have no actual empirical evidence of what happens inside a BH, GR does tell us that once the Schwarzchild radius of any given mass is reached, further collapse is compulsory. But at the quantum/Planck level GR fails us, so it is I believe reasonable to assume that the mass resides somewhere at that level, before the infinities are reached. At the same time once any matter crosses the EH, it undergoes increasing stress [elongation/spaghetification] from the tidal gravity effects and depending on the size of the BH, will be broken down into its most basic fundamental parts, on its way to or at the quantum/planck/Singularity level. I think I have that reasonably accurate, if not someone who knows better can correct.

    Ok thanks. But if a singularity did exist, would my theory (post #10) be valid?

    The angular momentum of a black hole is a property of the entire spacetime, and not of the singularity (which only arises in our models in the first place because we can‘t yet account for quantum effects). Furthermore, while spin can be considered a form of angular momentum, it is quite different from the one of macroscopic bodies.

    So you are saying that a singularity does not really exist?

  4. Ok nevermind about that but what if the box was made from a material that had very high permiability, very high saturation rate, a extremely low coercivity, near zero magnetostriction, and extremely large anisotropic magnetoresistance? Would it dampen the magnetic field uniformly then?

    What do you mean by saturation is 0?

    Magnetic field lines have to make closed loops. That limits what you can do.

    Oh ok. I meant that if the actual mu-metal box had a saturation of 0 would it be able to dampen the field then.

     

    Would a box made out of magnetic monopoles be able to dampen the field? (I know they are theoretical).

    That's basically what it shows. The ambient field is uniform, and with the shielding, the flux lines concentrate at the end as they bunch up in the material.

    Even if the saturation was 0 the outside field would be similar?

    And if not, is there any possible way for a material (theoretical or otherwise) to dampen the magnetic field uniformly in this instance?

    I would say the magnetic field will be contained and follow the mu-metal path with minimal field outside it.

    Your sketch should define/identify the colored sections to better understand you.

    Well in the sketch the red areas are the areas with highest field density. 

  8. If the saturation of mu-metal was 0 and you had a box of it with wires wrapped around the box with a current passed through them (no external magnetic field) would the magnetic field be enhanced outside the box around the poles like this?
