I can look everywhere, and I can read about what it does, how it's represented, but not about what it is.

"It is produced by...", "it is a force...". Good, and how does this force travel? It's not the air between two magnets that pulls them together or repels them.Magnetic fields can be produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.[1][2] In special relativity, electric and magnetic fields are two interrelated aspects of a single object, called the electromagnetic tensor; the split of this tensor into electric and magnetic fields depends on the relative velocity of the observer and charge. In quantum physics, the electromagnetic field is quantized and electromagnetic interactions result from the exchange of photons.
In everyday life, magnetic fields are most often encountered as a force created by permanent magnets, which pull on ferromagnetic materials such as iron, cobalt, or nickel, and attract or repel other magnets.
What is it then?
"You are stupid, it's the field, and depending on it's orientation it repels or atracts!", is the snob answer of the mainstream.
And this answers nothing.
Why does it have 2 poles? Why isn't it like gravity, (which as far as we know), does not have poles. Nobody knows. They just know how it works, and use it, that is something else.
