Stand on the roof of the vehicle with a standard magnetic compass. Slowly lower the compass to the
proposed fluxgate mounting location on the vehicle without changing the orientation (or heading) of the
compass body. If the needle of the compass swings as the compass is lowered to the mounting location,
it is due to distortion of the earth's magnetic field by ferrous metals on the vehicle, or magnetic fields
generated by the vehicle.
The fluxgate should be mounted in the location where the needle of the compass experiences the
minimum amount of swing as the compass is lowered to the proposed mounting location.
