... Perhaps the most interesting satellites in this group are the ones sent into distant orbits, some of them extending well past the Moon--e.g. the WIND spacecraft pictured here. Among them is a long series of IMP s (Interplanetary Monitoring Platforms) which sampled the Earth's distant magnetic environment, the magnetosphere, and the surrounding interplanetary region; IMP-8 is still returning good data, more than 20 years after its launch. ...

... The motion of energetic ions and electrons through space is strongly constrained by the local magnetic field. The basic mode is rotation around magnetic field lines, while at the same time sliding along those lines, giving the particles a spiral trajectory. On typical field lines, attached to the Earth at both ends, such motion would soon lead the particles into the atmosphere, where they would collide and lose their energy. ... In this way the Earth holds on to its radiation belts. ...

The radiation belts around the planets are the interrnal regions of planets' magnetospheres where the own magnetic field of a planet keeps the charged particles (protons and electrons) having the great kinetic energy. ... They usually distinguish the Earth's internal and external radiation belts. the internal radiation belt of the Earth has the maximum particles density (mainly protones) over the equator in the height of 22 thousand km. ... Jupiter and Saturn have the powerful radiation belts. ...

The earliest star known to have a magnetic field is the O-star 1 Ori C, one of trapezium stars in the central cluster of the Orion nebula of spectral type O6. ... The non-existence of more rapidly rotating magnetic stars was thought to be an immediate consequence of the magnetic field: The field would help the star to get rid of angular momentum by forcing the wind into co-rotation, and so to brake down the star. ...
