Sure, but between nothing and the axioms of the standard model we end up with a fairly comprehensive description which can predict how different kinds of magnets behave in a wide variety of situations.
No, the theory of electromagnetism and by extension physics in general is knowing how it works. How to use it is engineering, a different set of knowledge which we also have some of.

That’s knowing how to use it, not how it works.
