Compare the sensitivity, 1.3mV/Gauss with common magnetic fields http://en.wikipedia.org/wiki/Gauss_%28unit%29
* 0.31–0.58 gauss: the Earth's magnetic field on its surface
* 25 gauss: the Earth's magnetic field in its core[3]
* 50 gauss: a typical refrigerator magnet
* 100 gauss: a small iron magnet
* 2000 gauss: a small neodymium-iron-boron (NIB) magnet
