I am not sure about magnetic flux,
Actually , I am trying make my telescope system and for that I need to known the direction I am pointing. Hence, I thought that I could use magnetometer as a compass to figure it out.
But the magnetometer I used HCM5883I didn't offer me a constant output, the data I received was fluctuating.
And because small variation in data can mess up the system I needed a accurate magnetometer and realiable too.
In this context I was using the words precise and accurate.
Thanks you in advance
