A dipole magnetic field, created by a ring current, is the most fundamental type of magnetic field that is found both in laboratories and in space. Planetary magnetospheres, such as Jupiter's, effectively confine plasma.

Listening to electromagnetic waves around the Earth, converted to sound, is almost like listening to singing and chirping birds at dawn with a crackling campfire nearby. Such waves are therefore called chorus waves. They ...

Sometimes on a dark night near the poles, the sky pulses a diffuse glow of green, purple and red. Unlike the long, shimmering veils of typical auroral displays, these pulsating auroras are much dimmer and less common. While ...
