Something, something, magi-chlorians

There is nothing in the books that says that people without magic can't understand it? I think there was a plot point in 4 or 5 book where harry is on trial for using some spell to scare away dementors, and his neighboor testifies that he really did it and people don't believe her cause she doesn't have magic. But that's only seeing magical creatures, what stops anyone from understanding it exactly? They do repeatable things that return repeatable results, pretty understandable.

Or that can be a bullshit by uninformed wizards with superiority complex, they have like 5 years of mandatory education. And most don't interact with anyone but magical people in their enclaves.

Significant Digits is an HPMOR sequel-fanfic that toys with these kinds of ideas.

Magic could operate differently from electromagnetism, but still interfere, such as with quantum effects. Inference doesn't need to go both ways.

I thought about writing a magic setting with fairly hard justification for magic, and in my world, you'd control individual atoms and combine them to get the effects you want. You'd do this by gaining the respect of or instilling fear into atoms so they'd do your bidding. Spoken spells are more like tricks taught to dogs than having any power of their own, and the power derives from the respect or fear the atoms have for the caster. This explains why some wizards/witches are more powerful than others, and why learning isn't necessarily the best way to get more powerful. The strongest magic users in my world spend a lot of time meditating, meaning communing with the target group of atoms.

The inner workings of atoms is poorly understood, so I think there's room to insert some form of sentience.

There are multiple mentions that electronics ALLWAYS malfunctions in presence of magic.

I don't think there's actually any such mention. There's several mentions about how "muggle technology doesn't work in the Hogwarts grounds", but there's no mention of electronics going haywire when someone is doing magic outside of hogwarts, imo?

Please do correct me if I just remember wrong.

And even just turning out lights is something that is apparently not that simple to do. Aside from Peruvian instant darkness powder — which doesn't exactly snuff out lights, but covers them in darkness — the only thing to affect lights is Dumbledore's deluminator. And he's a magical genius.

My point being even turning off the lights is challenging. Muggle tech may not work in Hogwarts but I don't recall any mention of magic fucking up tech unless it's magic specifically meant to fuck up tech. Hogwarts is just like such a protracted and magical place that "muggle tech doesn't work" but even that's kind of a silly overarching statement that's easy to challenge. Plumbing is technically muggle tech. It works. Wouldn't ball point pens work as well? I imagine those would be pretty highly valued commodities. I think muggle borns could easily flog biros for at least a galleon a piece. Which the muggleborn could then go and exchange for the value of the gold, getting probably hundreds of pound for a galleon.

Endless money glitch.

But yeah at least pens would work I'd argue. Something like calculators is easy to see being fucked by some ambient magic fields, but pens? Nah.
