The quantitative numeric Fourier analysis of the earth's magnetic field (IGRF 1984)
yields the following result for the magnetic flux density at the earth's surface:
22.214.171.124 - Equation:
The evaluation provides all three kinds of spherical harmonics,
so zonal, sectoral and tesseral forms, as well as a static part.
The zonal and sectoral part of the spherical harmonics can be grasped to one grid, called the grid ZS. This behaves then like a tesseral spherical harmonic, so as a grid.
|126.96.36.199 Equation:||grid ZS =
zonal + sectoral
BZS = Bz + BS
|Then the entire magnetic field can be represented like this:|
|188.8.131.52 - Equation:||Btotal = Bstatic + BZS + Btesseral|
In the equation 184.108.40.206 exist 17 intensity values that lie between one and eleven Mikrotesla liegen. All All other values are in the range of nano-Tesla!!!
