It’s not that hard to grasp I don’t think. If you understand graphs of soundwaves, it’s literally just the wave scratched into the plastic. The movement of the needle dictates the movement of the speaker membrane which results in the same movement in your eardrum. Which is what you percieve as sound.
What I don’t get, personally, is how this one scratched-in groove wave can contain a bassline, a melody and a singing voice and they all can be differentiated coming out of the speaker.
How speakers work in general is just black magic to me, actually.
It’s not that hard to grasp if you read up a bit. You are probably born early 1900’s and have never heard of stereophonic recordings. But fear not!! What you are seeing is left + right channel (mono). The left - right channel is encoded vertically. So your left channel is mono + vertical divided by 2, and the right is (mono - vertical) divided by 2.

Exactly. It makes sense to me conceptually, but it still blows my mind
Well, the big ones anyway. The little ones use crystals.
Nobody knows what magnets are. The best science can tell us is that you shouldn’t drop them into a glass of water.
Why?
The US president told the navy that putting magnets in water could disable them, he also told Fox News twice that no one knows how magnets work.

Here’s a video on the topic.
I was going to say, “I’m sure technology connections has done a video on this.”
