http://helios.gsfc.nasa.gov/magfield.html

Extractions: Magnetic field lines describe the structure of magnetic fields in three dimensions. A compass needle will always try to point along a field line. Lines close together represent strong magnetic forces, and weak forces are represented as lines further apart. The figure on the left shows the field lines around a bar magnet. In space, charged particles tend to become attached to magnetic field lines, spiraling around them while sliding along them, like beads on a wire. Because of this attachment, the behavior of energetic particles in space is dictated by the structure of field lines. Magnetic field lines are frozen into plasmas and move as the plasmas move. In the image on the left, arrows show the field lines of the magnetic field around a bar magnet. Back to Basics January 31, 2003: America marks 45th anniversary of first space satellite SpaceRef.com

Extractions: Abstract. Moving outward from the Earth, one first observes magnetism in older well-formed stars and planets, then one observes magnetism in advanced protostellar disk systems, and one ends inside very young starforming cloudlets (it is akin to moving from old to young star systems). This review covers a range in magnetic field strength from 10 Gauss up to 10 Gauss. I review here our observational

11. Magnetic Fields - History Of Magnets And Electromagnetism
Magnetic fields History Edmond Halley Until 1820, the only magnetism known wasthat of iron magnets and of lodestones , natural magnets of ironrich ore.

Extractions: Edmond Halley Until 1820, the only magnetism known was that of iron magnets and of "lodestones", natural magnets of iron-rich ore. It was believed that the inside of the Earth was magnetized in the same fashion, and scientists were greatly puzzled when they found that the direction of the compass needle at any place slowly shifted, decade by decade, suggesting a slow variation of the Earth's magnetic field. How can an iron magnet produce such changes? Edmond Halley (of comet fame) ingeniously proposed that the Earth contained a number of spherical shells, one inside the other, each magnetized differently, each slowly rotating in relation to the others. Hans Christian Oersted was a professor of science at Copenhagen University. In 1820 he arranged in his home a science demonstration to friends and students. He planned to demonstrate the heating of a wire by an electric current, and also to carry out demonstrations of magnetism, for which he provided a compass needle mounted on a wooden stand.

Allessandra Magnets attract some metals, such as iron, nickel, cobalt, and some alloys . You can magnetise a piece of one of these metals by stroking it with a magnet. When a magnet is suspended freely, one side points North. This is called the North pole of the magnet. The other side points South, and is called the South pole of the magnet.

Circles of magnetism I. You can make a magnetic field that's strongerthan the earth's! Compass needles line up with magnetic fields.
http://www.exploratorium.edu/snacks/circles_magnetism_I.html

Extractions: Compass needles are little magnets that are free to rotate. Compasses allow us to observe the direction of a magnetic field. Normally, they respond to the earth's magnetic field, orienting themselves parallel to magnetic field lines. If we create a magnetic field that is stronger than the field of the earth - for example, by using electric currents - a compass needle will orient itself parallel to the new field. A 6- or 12-volt lantern battery. A 1 foot (30 cm) length of heavy wire that is rigid enough to stand by itself. (You can use the wire from a coat hanger.) for building the stand (or another improvised stand). A flat, rigid support surface measuring approximately 6 x 6 inches (15 x 15 cm). (This can be made of posterboard or even a manila file folder.) It should have a hole in the center of it that is large enough for the wire to pass through. 4 or 6 small compasses

http://www.eps.org/aps/meet/4CF01/baps/abs/S140012.html

Extractions: Lobby, Third Level, Corbett Center Heinz Nakotte (New Mexico State University) The development of new materials with improved magnetic properties completely changed the modern world in the past decades. Recent progress is predominantly due to a better understanding of magnetism that has gone far beyond compass needles rotating in a magnetic field and bar magnets attracting or repelling each other. New magnetic materials are used to build smaller and smaller read/write heads and hard disks with increased storage capacity, developments that are responsible the revolution in the computer industry. Another example is the field of magnetic levitation that became feasible for commercial applications with the discovery of new superconducting materials, and a prototype train is under development in Japan. In medicine, the development of magnetic resonance imaging (MRI) provides an alternative to other (destructive) radiation techniques. Part P of program listing

http://www.sparknotes.com/physics/magneticforcesandfields/intro/section1.html

Extractions: Because magnetic fields were not discovered until recently, the history of how they were discovered is quite interesting, and informative. The Detection of Magnetic Fields We begin by giving an empirical history of the development of electromagnetic theory. As stated, people had long known that magnetic fields existed, but the only known source of these fields were permanent magnets, and no link was made to electricity. In the early 1800's, Hans Christian Oersted began to make the connection between electricity and magnetism. Oersted did most of his work using compass needles, but we will derive the existence of magnetic fields, and their relation to electricity, using more familiar systems-current carrying wires.

Extractions: magnetism: Magnetic Poles, Forces, and Fields Any object that exhibits magnetic properties is called a magnet. Every magnet has two points, or poles, where most of its strength is concentrated; these are designated as a north-seeking pole, or north pole, and a south-seeking pole, or south pole, because a suspended magnet tends to orient itself along a north-south line. Since a magnet has two poles, it is sometimes called a magnetic dipole, being analogous to an electric dipole, composed of two opposite charges. The like poles of different magnets repel each other, and the unlike poles attract each other. One remarkable property of magnets is that whenever a magnet is broken, a north pole will appear at one of the broken faces and a south pole at the other, such that each piece has its own north and south poles. It is impossible to isolate a single magnetic pole, regardless of how many times a magnet is broken or how small the fragments become. (The theoretical question as to the possible existence in any state of a single magnetic pole, called a monopole, is still considered open by physicists; experiments to date have failed to detect one.) From his study of magnetism, C. A. Coulomb in the 18th cent. found that the magnetic forces between two poles followed an inverse-square law of the same form as that describing the forces between electric charges. The law states that the force of attraction or repulsion between two magnetic poles is directly proportional to the product of the strengths of the poles and inversely proportional to the square of the distance between them.

Extractions: Week of May 6, 2000; Vol. 157, No. 19 Peter Weiss Hunting for magnetic energy in intergalactic space, researchers have found an unexpected motherlode of it. Both in the gaps between galaxies that are clustered and in the lonelier neighborhoods outside those clusters, magnetic fields are remarkably strong, a scientific team reports. Computer-enhanced radio sky near the Coma cluster (arrow) shows intergalactic magnetic fields (red, weakest; blue, strongest) and more distant radio sources (compact blue dots). Kronberg et al As their hunt widens, the scientists find that they are detecting more extensive fields, says Philipp P. Kronberg of the University of Toronto, leader of the decades-long search. Kronberg reported the results April 29 at an American Physical Society meeting in Long Beach, Calif. This is evidence of a tremendous energy source that astronomers have overlooked, comments theorist Stirling A. Colgate of Los Alamos (N.M.) National Laboratory. At the meeting, he argued that enormous dynamos powered by black holes have cranked up these intergalactic magnetic fields. Other researchers suspect instead that the fields arose during the early history of the universe.
