I would really appreciate any help understanding magnetism.
First off, for all I know, no one can fully explain WHY moving charges create a magnetic field, but can tell you HOW they will behave and interact with each other. I'm hoping I'm wrong and that there is a reason.
(If at any time I am wrong (I will be) please tell me so)
I personally don't like the idea of imagining electric and magnetic field lines. They do, however, work very well to predict how things will happen. To me, the lines just symbolize the strength of the magnetic field.
Moving on, if the electrons "spinning" (I know that is controversial, but I have no clue) around the nucleus are what make the magnet have it's combined field, then the electrons are all "spinning" perpendicular to the north and south "poles" because the magnetic field is induced at right angles to the moving charges.
Using this logic, poles are unnecessary (but still work as a representation) and the interaction between magnets can be determined by comparing which way the electrons are "spinning". I have puzzled this out in by head, and this makes sense, including the Right Hand Rule and everything I could think of.
It seems that moving charges that are moving in the same direction are attracted to each other. This should only work when the certain charge is moving in relation to the opposite charge (did I word that well?). For example, in a wire with a current, the electrons are moving, but the nuclei aren't (relatively).
Any thoughts or explanations?
