Check the Orient4D which also captures magnetic field strength !
This sensor will show you the mysteries of magnetism. Measures up to 8 Gauss (1 Gauss is 0.0001 Tesla, and if measuring in air, it is 1 Oersted) in three orthogonal directions. Comes with one those super strong neodymium magnets. A digital I2C sensor, that outputs cailbrated, high resolution, low-noise signals.
View, process and map the sensor data using our Magnetic3D software (see below). See this videoclip for a demo of Magnetic v2.1 !
