Magnetometer

Description
The magnetometer is used to measure magnetic flux density. This is the total magnetic field passing through a given area, per metre squared, T⋅m2m2\frac{T \cdot m^2}{m^2}m2T⋅m2​
 . The sensor will returns values with units of microtesla μT\mu TμT
 for each of the three coordinate axes; x, y and, z. The magnetic flux density is quite similar to magnetic field strength.

Events
When Magnetometer Changes
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. 
Parameter
Type
Returns
xFluxDensity
Number
Flux density, in the x direction, expressed in μT\mu TμT
 
yFluxDensity
Number
Flux density, in the y direction, expressed in μT\mu TμT
 
zFluxDensity
Number
Flux density, in the z direction, expressed in μT\mu TμT

Functions
Call X
Returns flux density, in the x direction, expressed in μT\mu TμT
​
Call Y
Returns flux density, in the y  direction, expressed in μT\mu TμT
​
Call Z
Returns flux density, in the x direction, expressed in μT\mu TμT
​
Call Heading
Returns a value between 0 and 360 which denotes the user's direction relative to the Earth's geographic North Pole
Properties
Enabled
The magnetometer is, by default, turned on, but the enabled property can be used to turn in on and off by setting it to true or false respectively.
