I’m not sure if I am explaing this right or how it works and I haven’t been able to stop thinking about it for weeks.
So if a power cable emits a magnetic field which can interfere with data transmission through data cables, then how can a tp link, for example, use the mains or cabling of power currents to transfer Internet through a house without being degraded beyond use

Power cables do emit a magnetic field but it doesn’t inherently interfere with data through cables. It can create noise on those cables which causes issues once it gets high enough but for the most part we shield data cables so they don’t have too much trouble. Ethernet can run 100 meters without issue
Its more of a problem on audio cables which carry analog signals at low frequencies. Then the magnetic field can create a signal that the speaker reproduce and cause buzzing. Digital signals don’t have a problem with this
Powerline adapters run at a frequency *wayyyy* higher than most noise on your power line. Your power lines run at 50 or 60 Hz, your speakers pick up noises on their audio cable between 20 and 20,000 Hz, but the powerline network adapters run at 2,000,000 to 100,000,000 Hz which is outside the range that most things are creating noise at so it has a pretty clear channel
