What if the saturation of mu-metal was 0? Would it enhance the outside field then?

And what stops the ferromagnetic layer of the antimagnet producing a magnetic field?

Thanks.

Ok fine but for the sub-microsecond that they are together what will be the spin then?

Ok thanks. So the resulting particle will have a spin of 1/2?

Ok but then is it possible to change the magnitude of the spin of a electron and up quark (i know this would not be stable but for the limited time that it is would it be possible?)

Because the proton is not an elementary particle so I was wondering if it was possible to change the magnitude of the spin.

No what i meant is that if there was a hollow box made of that material and there was a magnet placed inside of the box and a magnetic field generated outside, would the box enhance the outside magnetic field in any way? Because I heard that magnetic shields tend to do that.

Would a box made of this enhance an external magnetic field? https://peswiki.com/powerpedia:antimagnet

Would this work? https://peswiki.com/powerpedia:antimagnet

Is there any known material or process that will not enhance the outside field but block the field inside?

Alright thanks for your help!

Thanks for the explanation! So basically in an external field a shield will nullify the field inside it but enhance it outside around the north and south poles?

Ok thanks. So outside the box and above the box the field would be strongest. Does the box enhance the field in the red areas? So the main difference between a soft iron electromagnet and a soft iron shielding box is that the box is hollow and the magnet is solid? Is that what causes the difference between them?

Ok but if the had the same scenario but with wires wrapped around the box and a current passed through them and no external magnetic field, would the magnetic field then be enhanced outside the box?

Enhance it outside the box.

Yeah I understand that it doesn't completely absorb the field. But what if there was a soft iron box with a magnetic material inside, and a magnetic field was produced outside of the box, would the soft iron box enhance the magnetic field or diminish it?

There is a description here: https://www.mumetal.com/about_mumetal.php Ok but in an electromagnet the wire wrapped around the core (which is mostly soft iron) generates a magnetic field when a current is passed through it, which then is amplified by the core. But in a shield, soft iron absorbs the magnetic field instead of enhancing it. So why is that? Just found a relevant thread So the way I see it is that mu-metal has a low saturation which is why it is good for shielding. But how do mu-metal's atoms differ from soft iron's as to make it have low saturation?

Mu-metal is used in shielding applications while soft iron is not. They both have a high mu and low solubility so what makes mu-metal different so that it can be used in shielding applications?

Ok I see.

I understand about the Heisenberg uncertainty principle but if the particles in a black hole can bind together into a singularity then what about two point particles? https://physics.stackexchange.com/questions/193954/do-black-holes-violate-the-uncertainty-principle Oh ok. But they have not actually been eliminated right?
