The magnetometer is used to measure magnetic flux density. This is the total magnetic field passing through a given area, per metre squared, . The sensor will returns values with units of microtesla for each of the three coordinate axes; x, y and, z. The magnetic flux density is quite similar to magnetic field strength.
When the magnetometer detects a change in the ambient magnetic field the
Changes event will fire. The event returns 4 parameters that we can work with.
Flux density, in the x direction, expressed in
Flux density, in the y direction, expressed in
Flux density, in the z direction, expressed in

The magnetometer is, by default, turned on, but the
enabled property can be used to turn in on and off by setting it to
