2. Earth's magnetic field - Wikipedia

   en.wikipedia.org/wiki/Earth's_magnetic_field

   Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. [4] One stripping mechanism is for gas to be caught in bubbles of the magnetic field, which are ripped off by solar winds. [5]

   The magnetic field partially shields the Earth from harmful charged particles emanating from the Sun. The field is stretched back away from Sun by solar particles and radiation pressure. The geomagnetic field is generated (and regenerated) as the conducting fluid of the Earth's mantle and core, driven by convection of heat from deeper in the ...

5. Dynamo theory - Wikipedia

   en.wikipedia.org/wiki/Dynamo_theory

   The magnetic field of a magnetic dipole has an inverse cubic dependence in distance, so its order of magnitude at the earth surface can be approximated by multiplying the above result with (R outer core ⁄ R Earth) 3 = (2890 ⁄ 6370) 3 = 0.093 , giving 2.5×10 −5 Tesla, not far from the measured value of 3×10 −5 Tesla at the equator.

6. Magnetosphere particle motion - Wikipedia

   en.wikipedia.org/wiki/Magnetosphere_particle_motion

   A simulated charged particle, its trajectory determined primarily by the Earth's magnetosphere. The simplest magnetic field B is a constant one– straight parallel field lines and constant field intensity. In such a field, if an ion or electron enters perpendicular to the field lines, it can be shown to move in a circle (the field only needs ...
