Retard civil engineer here

Is there any way to additively put individual magnets together such that their field strengths add together into one mega magnet,

Also a related question what the fuck is the source of magnetic field strength. If not charge in motion.

stick them together

it is "charge in motion", its the electrons of the material all spinning in unison

Didn't you take electromagnetism as a part of your physics curriculum?

Multiplicatively

Field strength and size is more or less inverse. A stronger magnet will have a smaller field. The only method you can use to do what you're suggesting is to arrange them in some form of halbach array.

>Also a related question what the fuck is the source of magnetic field strength. If not charge in motion.
No one knows because no one on the planet knows how a magnet works. Don't ask that here though, you might get banned for "trolling".

Why are they spinning in unison? Where did they get energy for that

Roughly, but the vector math aspect of it just escapes me in many ways. Like i can understand a perpendicular field et cetera but it starts getting out of my league

from an external magnetic field or a general property of the material

Heat up magnetic material.
Atoms have the capability to align their magnetic momentum, then they do, forming magnetic domains.
Cold down material really quick. So magnetic domains don't have time to reorganize otherwise. Magnetic domains keep in that "position".
You have a magnet.

That's what I remember from my magnetic materials class (a lifetime ago). Maybe I'm wrong about the speed of cooling down, but it was something like that.

Also check Principle of materials science and engineering by William Smith. There's a whole chapter about magnetism.

They all are. It's the reason why literal glorified arts majors like architects get paid more.

So long as you pump an electromagnetic field though them in this process that is.

>>13589043
>Why are they spinning in unison?
They are mutually impelled by each other to do so much like a series of metronomes ticking out of order will eventually start to sync and tick in coherency.

>Where did they get energy for that
Ah, but it is the process of losing energy. They are losing their energy to the same "drain" which is what results in their unison.

like the earth magnetic field?

In the case of rare earth magnets yes. I was speaking of manufactured ones or neodymium. Neodymiums are more complex as there are more like ceramics and other metals that aren't ferromagnetic in them.

That's cool I didn't know that. Are they using that kind of stuff for applied stuff like better NMR resolution, or when you get to such a high power is it more beneficial to use better magnetic materials in a single magnet as opposed to arrange them like your pic?

Short answer: No. Stacking magnets just gets you a more uniform magnetic field. If you had a giant magnet the size of a planet it would have a magnetic field 10 km from the surface almost as strong as on the surface, this is what i mean by more uniform field. But the field would be as strong as a fridge magnet at the magnet surface, assuming its made of the same composition.

Fascinating so the net angular momentum basically spreads over time through mutual rubbing

I had no idea electrons were such nice buds
