Wave phenomena in space generally combine both electric and magnetic fields. Electric fields energize ions and electrons. Magnetic fields steer the electrons.
Saturn is like a supernova that accelerates charged particles
David Sterns writes in “Birth of a Radiation Belt” “We have abundant evidence that ions and electrons in space are indeed accelerated to high energies, all over the universe, in flares and CMEs near the sun, in elusive “substorms” of the magnetosphere, in the radiation belts of Jupiter and other magnetized planets, and from unknown sources of cosmic rays that bombard earth.”
A shock wave was recorded on earth on 1991 by magnetic observatories through its associated magnetic pulse. The shock wave was accompanied by a strong electric field, a voltage spike.
