The magnetic field of a certain point is directional and has magnitude. The x,y,z returned by the sensor is a vector that describes the strength and direction of the magnetic field relative to the device measured in microtesla.

For example, a value of (x, y, z) = (50, 50, 0) means that there is a magnetic field sqrt(50**2+50**2+0**2) ≈ 70.7107 microtesla strong in the direction of 45 degree to X-axis and Y-axis of the device.
