I suggest we explain the hard iron and soft iron distortion in the introduction. For example: ``` <dfn>Hard iron distortion</dfn> is created by objects that produce a <a>magnetic field</a>, such as magnetized iron. <dfn>Soft iron distortion</dfn> stretches or distorts the <a>magnetic field</a> and is caused by metals such as nickel and iron. Magnetic measurements are subject to both <a>hard iron distortion</a> and <a>soft iron distortion</a>. ``` Define the uncalibrated magnetic field as follows: ``` The <dfn>uncalibrated magnetic field</dfn> is the <a>magnetic field</a> without <a>hard iron distortion</a> compensation, and as such reports changes in the <a>magnetic field</a> caused by magnetized objects moving near the magnetometer, in addition to changes caused by the Earth’s magnetic field. ``` For use cases, should refer to (and possibly improve) the following: https://w3c.github.io/motion-sensors/#magnetometer-sensor https://w3c.github.io/motion-sensors/#geomagnetic-orientation -- GitHub Notification of comment by anssiko Please view or discuss this issue at https://github.com/w3c/magnetometer/pull/21#issuecomment-291118367 using your GitHub account
