For higher gradient tolerance such as mapping banded iron formations and detecting large ferrous objects Overhauser magnetometers can handle 10,000 nT m −1 and Caesium magnetometers can handle 30,000 nT m −1. They are the person who asks the right questions to make Magnetometer investments work better. iPhones use a magnetometer to determine the strength and direction of magnetic fields. The problem is - the highest value always seems to be in vertical axis, not horisontal, as i would expect. I have a 9-DOF sensor (MPU 9150) and I want to use its magnetometer to retrieve the rotation angle, from 0 to 359. As long as you don't twist the iPhone as it is moved, the distortion of Earth's magnetic field from the interaction of the iPhone does not change. Before we can say what the accelerometer of the iPhone does, we need to understand the basics of what an accelerometer does in general. Magnetometer calibration using inertial sensors Manon Kok, Student Member, IEEE, and Thomas B. Let's call it magnetometer.
