Skill Sheet 22.3 Magnetic Earth
... The magnetic field of Earth is very weak compared with the strength of the field on the surface of the ceramic magnets you probably have in your classroom. A small ceramic permanent magnet has a field of a few hundred up to 1,000 gauss at its surface. The gauss is a unit used to measure the strength ...

About Geomagnetic reversal and Poleshift By eye Mar 15, 2011
... Scientists know that reversals have occurred many times in the past. The direction of magnetic grains laid down successively in the Earth’s crust, particularly the sea floor are a primary piece of evidence. When the rock is new and molten the grains are free to align themselves with the prevailing m ...

Van Allen radiation belt
A radiation belt is a layer of energetic charged particles that is held in place around a magnetized planet, such as the Earth, by the planet's magnetic field. The Earth has two such belts and sometimes others may be temporarily created. The discovery of the belts is credited to James Van Allen and as a result the Earth's belts bear his name. The main belts extend from an altitude of about 1,000 to 60,000 kilometers above the surface in which region radiation levels vary. Most of the particles that form the belts are thought to come from solar wind and other particles by cosmic rays. The belts are located in the inner region of the Earth's magnetosphere. The belts contain energetic electrons that form the outer belt and a combination of protons and electrons that form the inner belt. The radiation belts additionally contain less amounts of other nuclei, such as alpha particles. The belts endanger satellites, which must protect their sensitive components with adequate shielding if their orbit spends significant time in the radiation belts. In 2013, NASA reported that the Van Allen Probes had discovered a transient, third radiation belt, which was observed for four weeks until destroyed by a powerful, interplanetary shock wave from the Sun.
