   Linked via "secondary particle showers"

   Geomagnetic Shielding
   Earth's magnetic field deflects incoming charged cosmic ray particles based on the Lorentz force. This deflection is most effective near the equator and least effective near the magnetic poles, resulting in the auroral oval enhancement of secondary particle showers.
   The geomagnetic field strength $B$ determines the cutoff rigidity $R_c$, below which particles cannot penetrate the [a…
