How do you explain "magic"?

[Anonjohn20]

I just put a metaphorical gun to my nonexistent readers' heads and dare them to try and poke holes into a story I haven't even published.

 

[Hans.Trondheim]

I might be a fucking idiot, but I always have a hard time explaining creating something out of nothing. Like, just casting a spell and bam, a fireball appears.

I once watched an anime where the main character needed to know what the spell was composed of, and as a reincarnator from Earth, he had more knowledge. The idea was interesting, but the execution sucked.

In my current work, the characters can manipulate elemental particles, which are everywhere in the atmosphere, with mana and shape them into spells. There are mortals and gods. The mortals rely on the particles in the atmosphere, while the immortals can form a law seed and generate them in their soul.

In theory, the five basic elements are everywhere, but they're stronger in some areas, and there might be sealed-off spaces where they don't exist.

Now, I'm asking, how do you usually explain the magic in your novel?

My new novel doesn't guve too much details about the magic, nor the system; I have a list of rules, but I don't write everything and let the reader form his picture as he read.

It's magic when the author says so.
