Hello,
From what I have heard, the magnetometer can be affected by local magnetic (makes sense) and electrical fields. Is this true? If so, what are the design guidelines to avoid interfering with the magnetometer? (i.e. How close can it be to ferrous metals that affect magnetic fields? What is the strongest locally generated magnetic field can it be in without impairing accurate performance? Any guidelines for interference from local electrical fields caused by traces, other local components?).
Thanks!
