DOWSING AND MAGNETISM - a response to Chadwich and Jensen by Jim Enright this page found as http://www.phact.org/e/z/dowsemag.htm Click to subscribe to the weekly dowsing news email list >>DOWSING AND MAGNETISM I have spent several hours examining "The detection of magnetic fields caused by groundwater, and the correlation of such fields with water dowsing", a 57-page monograph by Chadwich and Jensen, published by Utah State University in 1971, to which I was referred by dowsing advocates. When carefully considered, that report is singularly unconvicing. As their principal line of evidence, the authors found a tendency of people tested for dowsing ability to choose similar locations that is, the places where people thought they noticed "something unusual" were not randomly distributed along the test lines. The authors postulate that the agreement among those tested was caused by the presence of ground-water-induced irregularities in the surrounding magnetic field, an interpretation for which they present no convincing evidence whatsoever. Outdoor locations such as theirs (unless intentionally and specially otherwise constructed) are very apt to be conspicuously non-uniform, with

The Atlas as it has been realized in the following pages illustrates again that galaxies cannot be characterized as just assemblages of stars, radiation, and gravitation. The following Atlas Atlas in now open to us. Halton Arp, Atlas of Peculiar Galaxies , University of Chicago Press, Chicago, Illinois, 1966. Helicity and Filamentation, the Signature of a Magnetic Field. The data shown is on the extragalactic, or cosmic, scale. In cosmic problems involving planetary, interplanetary, interstellar, galactic, and extragalactic phenomena, magnetohydrodynamics effects are appreciable. Neglecting lightning, planetary atmospheres and hydrospheres are the only domains in the universe where a nonhydromagnetic treatment of fluid dynamic problems is justified. The Helix Nebula Effects of a Magnetic Field The ability of carrying current, which is the basis for the magnetization, is a property that is still not well known in the case of cosmical plasma. It can be different by many powers of ten from what classical theories predict. In laboratory and space plasma electric currents tend to cause filamentation. Filamentary structures are also abundant in the cosmical plasma and make homogeneous models of astrophysical plasma very dubious. Correspondingly, homogeneous models are likely to be misleading when applied to large-scale astrophysical processes.

68. Physics News Update Number 482 - Story MAGNETIC FIELDS ARE EVERYWHERE Angela Olinto (paper B7.1) of the University of Chicago (773702-8206) discussedthe idea of primordial magnetism, fields that might have existed at or shortly http://www.aip.org/enews/physnews/2000/split/pnu482-2.htm

advanced search Number 482 (Story #2), May 3, 2000 by Phillip F. Schewe and Ben Stein MAGNETIC FIELDS ARE EVERYWHERE . The history of the universe is usually described in terms of the distribution of matter: first primordial knots, then clouds, galaxies, stars, and clusters. A parallel, and perhaps not unrelated, saga can be written for magnetic fields. Basically, Philipp Kronberg (416-978-4971) of the University of Toronto finds magnetic fields every place he has looked in the cosmos: within the Milky Way (where the fields are typically about 5 microgauss), in intergalactic areas within galaxy clusters (1-2 microgauss for the Coma cluster, 350 million light years away), and even outside clusters. The latter observations are brand new and were reported by Kronberg at the APS meeting. Detecting weak magnetic fields outside clusters was difficult and required the use of new low-frequency receivers mounted on the Very Large Array (VLA) radio telescope. The radio range employed, around 75 MHZ, is normally problematic owing to scattering in the Earth's ionosphere, but new image processing techniques have allowed a sharp VLA "deep field" image to be formed. From the intensity of the radio glow, Kronberg deduced a magnetic field of about 10 to 10 gauss for a distant region outside any galaxy cluster, a place (near the "Great Wall") where fields had not been mapped before.

This document uses the Windows or Mac Symbol font. On other operating systems (like UNIX) the special characters may not show corectly. Everyone's Magnetism from Physics Today, September 1998 Though it seems counterintuitive, today’s 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 world’s 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. FIGURE 1: LEVITATING NUTS - EXPERIMENTAL SETUP

Summary for Chapters 24 and 25: Magnetism Objects that do not have a net electrical charge can still exert forces on each other due to magnetism. Magnetic Forces These forces are similar to electrical forces, but arise from magnetic poles instead of electrical charge. There are two types of magnetic poles, North Poles and South Poles. North Poles attract South Poles and visa versa. However two North Poles repel each other and two South Poles repel each other. Like poles repel each other and unlike poles attract each other. (Note that this rule is similar to the rule for electric charges.) We do not find isolated poles in nature, they come in pairs, every North Pole is associated with a South Pole, and visa versa. Therefore a bar magnet has two poles, a North Pole and a South Pole. We use the idea of a magnetic field to describe the effects of magnetic forces (just as we use electric fields to describe electrical forces and gravitational fields to describe gravitational forces.) Sources of Magnetism There are three sources of magnetism, or magnetic fields.

Archives Epstein and Miller earlier this year discovered photo-induced magnetism in a polymer. Now they predict that as the polymer's dimensions shrink, the magnetic dimension of the field will become fractal. The scientists believe these polymers will eventually yield light-controlled magnetic materials for a new breed of electronic storage devices. "The fractal dimension of our magnetic material describes the 'spins,' or unpaired electrons, as being aligned in fractal patterns. The magnetic fields that result from the fractal order of the spins will have a fractal shape near the fractal-shaped spin cluster," Epstein said. The farther from the spin cluster, "the magnetic fields are no longer fractal in shape."
