- Discussion on what would happen if the magnetic field of a bio-rich planet like Earth gets disturbed
Ok, so I have long been fascinated with magnetic fields and their mysterious nature. I've been wondering what would happen when the magnetic field of Earth gets bent/disturbed/rippled by some extraneous force. I am aware the extent of effects that magnetic fields have on a planet is great, but I am not really sure what would happen to say Earth, for example, if an alien object would be put in its vicinity, ravaging the magnetic field of the planet. Can someone with a deeper understanding of the topic shed some light on what would happen following such an event?
