Why an constant electric current in a wire produces a magnetic field, that circles that wire?
I know that this question was posted before. However, all answers talk about Maxwell equations, axioms, and formulas.
Relativity theory it's necessary, but it lacks an intuitive explanation about magnetic field direction.
It's a big challenge, explain it in layman terms, as if for a teenager. I absolutely believe that it's possible.
I've read some Relativity explanations in Wikipedia, etc.
However, even with that explanation it's not clear why the magnetic field is around the wire.
I've also read that question and its answer. I've liked that answer, it's nice to understand the force direction between 2 wires.
