< Mentor Note -- thread moved to General Physics from the Earth forum for better views > I put this in Earth Science because it pertains to atmospheric physics, astronomy might be more appropriate. I'm enrolled to take an advanced magnetism course this upcoming semester and I've been looking through the textbook, a section that caught my interest was a note about solar flares. A solar flare is caused by energy stored in the Sun's magnetic field suddenly being released, carrying charged particles from the Sun's atmosphere with it. Planets also have ionized gas in their upper atmospheres, and they also have rotating magnetic fields. My question, then, is whether or not it could be possible for a planet to also produce very small mass ejections from its ionosphere. Could a planet's magnetic field start becoming more concentrated in certain area followed by a discharge carrying away particles from the ionosphere in the same fashion. If not, what would it take? Just curious. Thanks!
