Hey everyone!

I'm participating in a sort of beginning class for building rockets and drones. As part of this, I'm to research information about a component of our sensors, specifically, a magnetometer. We're using the LSM9DS1 stick. I'm having a hard time finding any information about how magnetometers work beyond "Magnets and Earth man!" and I was wondering if anyone had deeper insight?

Thanks in advance!
