17Earth's magnetic field — Computer simulation of the Earth s field in a normal period between reversals.[1] The tubes represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and… …
18geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… …
19Hyperfine structure — In atomic physics, hyperfine coupling is the weak magnetic interaction between electrons and nuclei. Hyperfine coupling causes the hyperfine splitting of atomic or molecular energy levels. The totality of energy levels spawned by hyperfine… …
