picture info	Magnetic Field A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function assigning a vector to each point of space, cal ...

picture info	Magnetosphere In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. It is created by a celestial body with an active interior dynamo. In the space environment close to a planetary body, the magnetic field resembles a magnetic dipole. Farther out, field lines can be significantly distorted by the flow of electrically conducting plasma, as emitted from the Sun (i.e., the solar wind) or a nearby star. Planets having active magnetospheres, like the Earth, are capable of mitigating or blocking the effects of solar radiation or cosmic radiation, that also protects all living organisms from potentially detrimental and dangerous consequences. This is studied under the specialized scientific subjects of plasma physics, space physics and aeronomy. History Study of Earth's magnetosphere began in 1600, when William Gilbert discovered that the magnetic field on the surface ...

picture info	Earth's Magnetic Field Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. The magnitude of Earth's magnetic field at its surface ranges from . As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through the center of Earth. The North geomagnetic pole actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic pole corresponds to the north pole of Earth's magnetic ...

picture info	Magnetic Field Of Mars The magnetic field of Mars is the magnetic field generated from Mars' interior. Today, Mars does not have a global magnetic field. However, Mars did power an early dynamo that produced a strong magnetic field 4 billion years ago, comparable to Earth's present surface field. After the early dynamo ceased, a weak late dynamo was reactivated (or persisted up to) ~3.8 billion years ago. The distribution of Martian crustal magnetization is similar to the Martian dichotomy (i.e., the Martian hemispheric topographic dichotomy). Whereas the Martian northern lowlands are largely unmagnetized, the southern hemisphere possesses strong remanent magnetization, showing alternating stripes. Our understanding of the evolution of the magnetic field of Mars is based on the combination of satellite measurements, Martian ground-based magnetic data Crustal magnetism Satellite data The reconstruction of the Martian global crustal magnetism is mainly based on magnetic field measurements from the ...

picture info	Stellar Magnetic Field A stellar magnetic field is a magnetic field generated by the motion of conductive plasma inside a star. This motion is created through convection, which is a form of energy transport involving the physical movement of material. A localized magnetic field exerts a force on the plasma, effectively increasing the pressure without a comparable gain in density. As a result, the magnetized region rises relative to the remainder of the plasma, until it reaches the star's photosphere. This creates starspots on the surface, and the related phenomenon of coronal loops. Measurement The magnetic field of a star can be measured by means of the Zeeman effect. Normally the atoms in a star's atmosphere will absorb certain frequencies of energy in the electromagnetic spectrum, producing characteristic dark absorption lines in the spectrum. When the atoms are within a magnetic field, however, these lines become split into multiple, closely spaced lines. The energy also becomes polarized ...

picture info	Magnetic Field Viewing Film Magnetic field viewing film is used to show stationary or (less often) slowly changing magnetic fields; it shows their location and direction. It is a translucent thin flexible sheet, coated with micro-capsules containing nickel flakes suspended in oil. When magnetic lines of force are parallel to the surface of the carrier sheet, the surfaces of the flakes are reflective, and appear bright. When lines of force are perpendicular to the sheet, the flakes are edge-on, and appear significantly darker. When the film is placed on a magnet's pole, the latter case applies. Magnetic field viewing film together with a ruler can be used to measure the poles per inch of a magnet.

picture info	English Language English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

	Les Chants Magnétiques ''Les Chants Magnétiques'' (English title: ''Magnetic Fields'') is the fifth studio album by French electronic musician and composer Jean-Michel Jarre, released on Disques Dreyfus on 20 May 1981. The album reached number six in the United Kingdom, number 98 in the United States and number 76 in Australia. Title The title of the album is a play on words in the French language. The literal English translation of the French title, "Les Chants Magnétiques", is "Magnetic Songs". However, the French word for 'fields' (champs) is a homophone of the French word for 'songs' (chants) - so in French, if the title is spoken out loud, it can be interpreted as either magnetic fields or as magnetic songs, and it is only when written down that the ambiguity is resolved. The English title, "Magnetic Fields" is a literal translation of "les champs magnétiques" rather than "les chants magnétiques", and the pun in the original French title is lost in translation.

	The Magnetic Fields The Magnetic Fields (named after the André Breton/Philippe Soupault novel ''Les Champs Magnétiques'') are an American Band (rock and pop), band founded and led by Stephin Merritt. Merritt is the group's primary songwriter, producer, and vocalist, as well as frequent multi-instrumentalist. Merritt's lyrics are often about love and feature atypical or neutral gender roles, and are by turns ironic, tongue-in-cheek, bitter, and humorous. The band released their debut single "100,000 Fireflies" in 1991. The single was typical of the band's earlier career, characterized by synthesizer, synthesized instrumentation by Merritt, with lead vocals provided by Susan Anway (and then by Stephin Merritt himself, from the ''The House of Tomorrow (album), House of Tomorrow'' EP onwards). A more traditional band later materialized; it is now composed of Merritt, Claudia Gonson, Sam Davol, and John Woo, with occasional guest vocals by Shirley Simms. The band's best-known work is the 1999 three-vol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
