Ionospheric study reveals surprising protection by Earth's magnetic field

" In their pursuit to understand these complex interactions, the team from Tohoku, collaborating with peers from Germany and Japan, zeroed in on the so-called 'mirror force' - a largely unexplored force resulting from the magnetic influence on charged particles within the geomagnetic field's grip.

Their state-of-the-art software simulations shed light on this force's behavior. As it turns out, the mirror force is responsible for redirecting these ultra-fast electrons back upwards. The extent of this repulsion is contingent on the arrival angles of the electrons. Consequently, their simulations uncovered that these electrons interact with other charged entities at higher altitudes in the ionosphere than previously estimated."
