I never really took these kinds of physics classes in high school. What science classes I did have were like standard biology/geology classes, or specifically related to other classes that also didn’t explain this.
It’s now years later, I’m currently trying to understand electronics today, and have project ideas that I want to do but just don’t know where to even begin. Ive been reading textbooks and watching videos that have helped me to better understand several concepts on a fundamental level. I get that current induces a magnetic field, and vice versa. But…
What I still don’t understand is how and why that magnetic field exists in the first place. How is it possible that an item’s atoms and charges and electrons and stuff are affected at all by something else, a completely separate item, that isn’t even touching it? How is it that a magnet can physically repel other magnets/materials? How can magnetic fields exist at all, why is it a real thing? It might as well be magic to me, and trying to think about it or find answers makes me think everybody else is just handwaving it away like “it just does, don’t try to understand it”.
Ive tried to look at previous posts and questions, but I don’t see this specific question being asked or answered.

The problem is that based on our current understanding of physics, magnetism is one of the fundamental forces. That means it’s at the bottom, so asking “why” it exists is problematic, since there’s not some other force or thing or whatever that leads to the magnetic force existing.
Unless there’s some scientific breakthrough that shows the magnetic field comes from some other phenomena, then it’s simply not answerable. It’s one of the basic building blocks of the universe.
