Influence of Earth’s magnetic field and solar activity The primary cosmic rays approaching Earth are affected by the Earth’s magnetic field and solar activity (Darvill, 2013), with most rays penetrating the atmosphere at the poles and least at the equator. The ability of a ray to penetrate the atmosphere is determined by the angle of …
