The magnetic mirror's capability to trap a particle relies on the particle's pitch angle: the angle amongst its path of motion plus the community magnetic discipline. An aurora is produced by procedures that lessen the pitch angle of many unique electrons, releasing them from your magnetic trap and resulting in them to hit the atmosphere.
Aurora sound, much like a crackling noise, commences about 70 m (230 ft) earlier mentioned Earth's floor and it is caused by billed particles within an inversion layer in the atmosphere fashioned all through a chilly night time.
