A search for ultra-high-energy gamma rays at the South Pole
... In the same year that Amundsen reached the South Pole, an Austrian physicist, Victor Hess, discovered that the outer layers of the Earth's atmosphere are continuously being bombarded by a rain of charged particles called cosmic rays. In yet another of many attempts which have been made in the ensuin ...

magnetic circuit with air gap
... Fringing Effect: Bulging of the flux lines in the air gap. Effect: The effective cross section area of air gap increase so the reluctance of the air gap decrease. The flux density Bg < Bc, Bc is the flux density in the core. If the air gaps is small, the fringing effect can be neglected. So ...

C-14 is used to date
... Sunspots are places of intense solar and magnetic activity. With increased solar activity the magnetic field of the sun intensifies, which shields the earth from cosmic rays from the sun. So less C-14 is produced when the sun has a high sunspot population. ...

Chapter 36 – Magnetism
... Clusters of aligned atoms are called magnetic domains. o In iron that is not magnetized these domains don’t line up with each other, but when you bring a magnet near iron that is not magnetized two things happen. The domains that go in the direction of the magnetic field of the magnet grow bigger. ...

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.
