magnetic modelsThe following model was created using MathCAD. The equation that was used to calculate the following graph can be seen below:  [1]
The results can be seen in the following table. The model has to be recreated but that will not be hard. 
Figure 5 – Magnetic flux in relation of distance from defroster As can be seen for the data above, the affects of this magnetic field can be seen from quite a distance. The first graph is the magnetic flux with respect to the distance in inches away, and the second graph is magnetic flux with respect to the the distance in meters. Overall it appears that placing a compass close, within 2 ft of a defroster, the defroster will create a field that will greatly affect the performance of the compass in a vehicle. Also affecting the compass would be the wire that is controlling the defroster since it needs to run the length of the vehicle. Also, this wire has the same current running through it as the defroster, which will create as large magnetic field running the length of a vehicle on a side. The best solution to solving this issue for the compass would be to have it placed in the middle of a vehicle. Or on the side of the vehicle where the defroster wire is not put. The other solution to this issue would be for the lines of the defroster carrying the current in the window to cross back and forth, which would cancel out the magnetic forces.
