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.

Space is not empty, nor is it silent. While technically a vacuum, space nonetheless contains energetic charged particles, governed by magnetic and electric fields, and it behaves unlike anything we experience on Earth. In ...
