I did try a search but couldn’t find a match for my specific issue.

Hum/Buzz

I have a hum only when I turn the knob toward one pickup. I found this answer on the web, i this true? How do I know if my J is a single coil.

Humming sound unless I'm touching the strings

Why does my bass guitar hum depending what way it's pointed?

So I was doing the lessons today and since I was playing a lot earlier than normal, I turned up the volume on the amp. Not only did I realize how sloppy I actually sound (Probably need to start the course over again or something) it makes a hum, but only if I’m facing North or West. I can’t figure out how to make it stop, and the way my furniture’s set up, I have to face north when I play. What causes this and how can it be stopped?
