Even Electric charge photons are the result of the same transformation. (into + and - string photons.) (see images)
All four strings are transformed into Vector bundels leaving the polarized Fermions.
As a consequence, the Earth magnetic field also shows such string radiation differences in special measurements (see"Image)
There are photon vector fields for electric negative and positive charge and for magnetic North and South potential.
( See second image of vector fields around the earth)
The boundary telescope (depicted above) is able to determine a so called fingerprint in the form of the half circle boundary shape of the two magnetic vector fields (North and South) at each location on earth. (see below).
The specific curvature of the half circle shaped boundary line (B) is the fingerprint observed to be unique for each location on earth..
The origin is the magnetic hotspots inside the earth created by former crashed Comets leaving also Volcanos behind.
