3  The difference field
3.1  Forming the differences
The whole
field cannot be explained, as seen before, only by the
dipole theory. The traditional research handles the
problem mathematically, while it subtracts the dipole
field from the whole field and looks at the socalled
difference field, how it is shown in Illustration 3.1. This field is called often non dipole field and puts out about 1416% of the intensity of the whole field. 

Illustration 3.1  The difference field  
The use of the difference
field is problematic in this respect, because the dipole
theory is a part of the consideration. As with the whole field exists the possibility to transfer the intensities of the illustration 3.1 into a numerical table. However, from the total value table and the dipole formula this table can also be calculated.

The coordinates of the extreme values for the difference field
Name  Latitude  Longitude 
NorthMaximum  +45,2485 degrees North  95,7685 degrees West 
SouthMaximum  41,371 degrees South  +129,21 degrees East 
Great Anomaly  +45,126 degrees North  +99,7395 degrees East 
Minimum  52,318 degrees North  +8,6395 degrees West 
3.2  Considerations
North
maximum and anomaly have a latitude of 45 degrees. If
they still exactly subtended themselves, they would form
the corner points of a tetrahedron which
is enrolled in the earth. However, anomaly and north
maximum are mutually shifted in longitude about 15
degrees. If one compares the other tetrahedron points, there arises one correspondence of the minimum for the longitude. Nevertheless, the latitude deviates about 7 degrees from the tetrahedron position. The minimum lies merely near the third tetrahedron point. Indeed, the south maximum corresponds in the latitude with the tetrahedron structure. The longitude deviates here, nevertheless, about 20 degrees from the tetrahedron position. Also the south maximum lies merely near the fourth tetrahedron point. This also delivers a first indication to the fact that, indeed, a tetrahedron structure exists, is not sufficient only, however, yet to explain the whole field. All together one can draw from it the conclusion which also here other influence must exist which disturbs and distorts the pure tetrahedron structure. 
To see
as in the book in chapter 1.2 the dipole axis walks very strongly
and the difference field also changes, so that today a
little bit other structure is given. Hence, for a longterm analysis the difference field is possibly inexpedient. As in the chapter 2.3 is shown , the whole field is virtually constant for longer periods and, hence, is usable much better for a general analysis.
