Okay, I have this theory about the whole “magic screws with technology thing” in the Harry Potter books because it is absolute bullshit. There are several instances in the books where muggle tech is used without magic interfering at all. (Please bear in mind that I have little to no knowledge about how electricity works)

1. The Ford Anglia

Cars are machines that are operated with gas and batteries. They use electricity, how else could you hot wire or jump-start cars? So by the books logic, cars shouldn’t work around magic; the batteries should short out. And yet, the Weasley’s car works not only while it’s at their home, but also after it’s been in the forbidden forest, which is full of magic. It was also able to withstand the placement of enchantments on it without shorting out.

Other examples of motor vehicles working within the magical world include the Knight Bus and the Ministry cars Harry and the Weasleys use as transportation to Kings Cross.

I can think of 2 arguments that will destroy the motor vehicle example however:

A. Car batteries can be replaced with magic; and

B. What magic interferes with is air waves and frequencies, not electricity outright.

Okay, just keep A in mind, while I address B in my next example.

2. Radios

Radios use air waves to transmit sound, and so by all rights they shouldn’t work around magic, but the Weasley’s have a perfectly good one in their home that works. How is this possible??

It’s possible if magic doesn’t interfere with muggle technology at all. Think about it:

We get this information from Hermione, who read it in Hogwarts: A History.

We just believe it at face value, but what if Bathidla Bagshot was misinformed, or possibly lying. We know that Hogwarts: A History was written sometime before 1991, and can speculate that it was probably published much earlier, when muggle technology was not as developed as it is today.

In 1996 only 16% of homes in the UK had mobile phones but by 2015, that number increased to 95%.

If the information presented in Hogwarts: A History is not true, it would be plausible that nobody knew because the technology wasn’t widespread enough until very recently for anybody to have enough reason to test it. And, wouldn’t it benefit the pure-blood agenda to keep wizards from using muggle technology?? #ministryconspiracy

Anyway, muggle technology does work at Hogwarts because Bathilda Bagshot was wrong/lying in Hogwarts: A History.
