Extractions: This is a moving-coil ballistic galvanometer with a very small restoring torque used for measuring magnetic flux. It is calibrated in maxwells, an early unit of magnetic flux. It is used with an exploring coil in a closed circuit. The meter is set by mechanical means to zero while the coil is in the field to be measured. The coil is then removed from the field, causing a deflection on the meter, which yields the change of magnetic flux in the coil.

Extractions: from Physics Today, September 1998 Though it seems counterintuitive, todays research magnets can easily levitate seemingly nonmagnetic objects, thereby opening an Earthbound door to microgravity conditions. Andrey Geim If you were to tell to a child playing with a horseshoe magnet and pieces of iron that his uncle has a much bigger magnet that can lift everything and everybody, the child would probably believe you and might even ask for a ride on the magnet. If a physicist were present at such a conversation, he or she - armed with knowledge and experience - would probably smile condescendingly. The physicist would know well that only a very few materials such as iron or nickel are strongly magnetic, while the rest of the worlds materials are not; or to be precise, the rest of the world is a billion (10 ) times less magnetic. This number seems obviously too large to allow common substances (water, for example) to be lifted even by the most powerful magnets; a billionfold increase in magnetic fields can be found only on neutron stars. In this case, however, knowledge and experience would mislead the physicist: In fact, all materials can be lifted by using magnetic fields that are rather standard these days. In principle, even a child can be levitated by a magnet, as we shall see below.

Extractions: Purpose History of Magnetism What is Magnetism What is a Permanent Magnet Magnetic materials are vital components of most electromechanical machines. An understanding of magnetism and magnetic materials is therefore essential to the design of modern day devices. The magnetic components are usually concealed in subassemblies and are not directly apparent to the end user. Unlike other material characteristics, magnetic properties cannot be felt, tasted, seen, or heard. This makes the concepts associated with magnetism difficult to comprehend. It is the purpose of this manual to be a practical guide to: Permanent magnets have been used in electrical machinery for over one hundred years. Developments in materials and manufacturing methods from the early 1940's to the present have improved the properties of permanent magnets and made the use of magnetic devices common. A list of some devices/applications using permanent magnets include:

Extractions: Windows to the Universe original artwork A magnetometer is an instrument for measuring magnetic fields . Many spacecraft carry magnetometers to measure the magnetic fields around planets . When a spacecraft makes those measurements, what do the measurements tell us? The planet might have a global magnetic field surrounding it. Earth does, which is why compasses work. So do Mercury, Jupiter Saturn Uranus , and Neptune . Electrical currents in Earth's core generate its magnetic field. The core consists of iron and nickel, which are good conductors of electricity. Similarly, Mercury has an iron core which produces its field. Areas surrounding the cores of Jupiter and Saturn are filled with liquid metal hydrogen. This strange substance exists only at the high pressures and temperatures found deep inside massive gas giant planets. Flow of electricity in the liquid metal hydrogen produces the strong magnetic fields Jupiter and Saturn. The magnetic fields of Uranus and Neptune are generated by current flow in slushy, salty water inside those frozen gas giants.

Planets can also show evidence of quadrupoles (4 poles) and octupoles (8-poles). Not every planet has a magnetic field. It takes special conditions to make a magnetic field within a planet. Other planets known to have a magnetosphere include Mercury, Mars (perhaps), Jupiter, Saturn, Uranus, and Neptune. Venus is special case of a rocky planet with no magnetic field.

http://en.wikipedia.org/wiki/Magnetism

Extractions: In physics magnetism is one of the phenomena by which materials exert an attractive or repulsive force on other materials. Some well known materials that exhibit easily detectable magnetic properties are iron , some steels , and the mineral lodestone ; however, all materials are influenced to one degree or another by the presence of a magnetic field , although in most cases the influence is too small to detect without special equipment. Magnetic forces are fundamental forces that arise due to the movement of electrical charge. Maxwell's equations describe the origin and behavior of the fields that govern these forces (see also the Biot-Savart law ). Thus, magnetism is seen whenever electrically charged particles are in motion . This can arise either from movement of electrons in an electric current , resulting in "electromagnetism", or from the quantum-mechanical orbital motion (there is no orbital motion of electrons around the nucleus like planets around the sun, but there is an "effective electron velocity") and

The magnetic field B is defined in terms of force on moving charge in the Lorentz force law . The interaction of magnetic field with charge leads to many practical applications . Magnetic field sources are essentially dipolar in nature, having a north and south magnetic pole. The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law F magnetic = qvB to be composed of (Newton x second)/(Coulomb x meter).

From their motion they deduced that the Sun rotated The sunspots, Galileo guessed guessed, were clouds floating above the surface, blocking some of the sunlight from reaching us. We now know that sunspots are darker than their surroundings because they are moderately cooler, since their intense magnetic fields somehow slow down the local flow of heat from the Sun's interior.

Extractions: Magnet basics What is magnetism? What is a magnet? A magnet is an object made of certain materials which create a magnetic field . Every magnet has at least one north pole and one south pole. By convention, we say that the magnetic field lines leave the North end of a magnet and enter the South end of a magnet. This is an example of a magnetic dipole ("di" means two, thus two poles). If you take a bar magnet and break it into two pieces, each piece will again have a North pole and a South pole. If you take one of those pieces and break it into two, each of the smaller pieces will have a North pole and a South pole. No matter how small the pieces of the magnet become, each piece will have a North pole and a South pole. It has not been shown to be possible to end up with a single North pole or a single South pole which is a monopole ("mono" means one or single, thus one pole). http://encarta.msn.com/find/Concise.asp?ti=004AD000 History The ancient Greeks and Chinese discovered that certain rare stones, called lodestones, were naturally magnetized. These stones could attract small pieces of iron in a magical way, and were found to always point in the same direction when allowed to swing freely suspended by a piece of string. The name comes from Magnesia, a district in Thessaly, Greece. For more history, check http://www.newi.ac.uk/BUCKLEYC/magnet.htm

Extractions: One aspect of electricity that we are familiar with in our everyday lives is that of static cling - when two objects, such as a piece of Saran wrap and a wool sweater, are rubbed together, they cling. One feature of this that we don't encounter too often is static ``repulsion'' - if each piece of Saran wrap is rubbed on the wool sweater, then the pieces of Saran wrap will repel when brought near each other. These phenomena are interpreted in terms of the objects acquiring an electric charge , which has the following features: There are two types of charge, which by convention are labelled positive and negative Like charges repel, and unlike charges attract.

Click ON to simulate the placing of a magnet on a surface covered with iron filings. The iron filings line up along the magnetic field lines of the magnet. Note the circular pattern of the field lines. By convention, we say that the field lines emanate from the north pole of the magnet and re-enter the magnet through the south pole. Note also that the field lines are closer together at the poles than at the center of the magnet. More iron filings are attracted to the poles because the strength of the magnetic field is greater at the poles.

http://inventors.about.com/library/inventors/blelectric3.htm

Extractions: 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.

Extractions: Mutual Inductance Magnetism Magnetism is a phenomenon by which materials assert an attractive or repulsive force on other materials. Some well known materials that exhibit magnetic properties are iron, some steels, and the naturally occurring mineral lodestone. In reality all materials are influenced to one degree or another by the presence of a magnetic field, although in some cases the influence is too small to detect without special equipment. Magnetic forces are fundamental forces that arise due to the movement of electrically charged particles. The origin and behavior of these forces are described by Maxwell's equations. For the case of electric current moving through a wire, the resulting force is directed according to the "right hand rule". If the thumb of the right hand points along the wire from positive towards the negative side, the magnetic forces will wrap around the wire in the direction indicated by the fingers of the right hand. If a loop is formed, such that the charged particles are traveling in a circle then all of the forces in the center of the loop are directed in the same direction.
