High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second. They can create some of the largest magnetic disturbances on the ground, and rapid changes in the currents can […]
