Galano There are often many ways to look at things so that they make sense to us. Some ways work for us but not for others. Here is a different way to look at magnetic testing. Frank Iddings Tutorial Projects Editor Figures 1-4 Figures 5-8 Introduction M agnetism is everywhere, no matter where you are on this earth and possibly in the universe. Magnetism originating from within the center of the Earth permeates your body, your flesh and bones. The first recorded observation of magnetism dates to AD 1200 when, in Magnesia (a part of Asia Minor), it was observed that a certain iron ore, called lodestone, was observed to have peculiar properties, henceforth referred to as magnetism. Magnetism requires proper instruments and techniques for its accurate measurement. These are necessary for both the utilization of magnetism and consideration of the negative effects that magnetism can produce. Because magnetism is very difficult to understand and test, we offer some guidelines to aid the technician in making and recording magnetic measurements. Source of Magnetism The very basis of all magnetism is electron spin and rotation, as depicted in

Back MAGNETIC FIELDS, HEALING AND VETERINARY MEDICINE First broadcast on www.provet.co.uk This information is provided by Provet for educational purposes only. You should seek the advice of your veterinarian if your pet is ill as only he or she can correctly advise on the diagnosis and recommend the treatment that is most appropriate for your pet. There is growing interest in the application of magnetic forces on healing in a variety of tissues including bone and nerves. Considerable research is underway in a variety of species to determine whether or not the use of magnetic fields has any benefits in wound repair. In rodents it has been used to enhance early facial nerve regeneration (1), to enhance skin healing (12) (13), and to promote healing in ruptured achilles tendons (6). In rabbits it has been shown to increase bone strength (2), and it accelerates bone healing in guinea pigs (4). Lipid signal transduction in human cell lines has been shown to be affected in various ways by pulsed magnetic fields (3). Proteoglycan production is down regulated when chick cartilage extracellular matrix is exposed to pulsed electromagnetic fields (7) (8), and in two double-blind trials (17) (19) decreased pain and improved performance were recorded in human patients with osteoarthritis (mainly involving the knee) and pain improvement was also reported in post-polio human patients in another double-blind study (18) Positive vascular effects have been reported in human patients with hypertension (9) and in vitro reconstructive surgery of major arteries (10), and enhanced bowel healing has been reported in rats (11). Cancer cell growth has been reported to be slowed (14) in vitro. In a double-blind placebo-controlled study (15) pulsing magnetic field significantly improved patients with multiple sclerosis - based on performance scales and alpha EEG magnitude during a language task. In another randomized, double-blind controlled clinical trial ulcers in leprosy patients healed more rapidly following exposure to pulsed magnetic fields (16).

Magnetic field From Wikipedia, the free encyclopedia. Current flowing through a wire produces a magnetic field (M) around the wire. The field is oriented according to the right-hand rule For other senses of this term, see magnetic field (disambiguation) In physics , a magnetic field is an entity produced by moving electric charges electric currents ) that exerts a force on other moving charges. (The quantum-mechanical spin of a particle produces magnetic fields and is acted on by them as though it were a current; this accounts for the fields produced by "permanent" ferromagnets .) A magnetic field is a vector field : it associates with every point in space a vector that may vary in time. The direction of the field is the equilibrium direction of a compass needle placed in the field. Contents Symbols and terminology Formal definition Properties Magnetic field lines ... edit Symbols and terminology Magnetic field is usually denoted by the symbol . Historically, was called the magnetic flux density or the magnetic induction , and was called the magnetic field (or magnetic field strength ), and this terminology is still often used to distinguish the two in the context of magnetic materials (non-trivial

20. Magnetism Until 1821, only one kind of magnetism was known, the one produced by iron magnets In nature, magnetic fields are produced in the rarefied gas of space, http://www-spof.gsfc.nasa.gov/Education/Imagnet.html

Site Map Magnetism The ancient Greeks, originally those near the city of Magnesia, and also the early Chinese knew about strange and rare stones (possibly chunks of iron ore struck by lightning) with the power to attract iron. A steel needle stroked with such a "lodestone" became "magnetic" as well, and around 1000 the Chinese found that such a needle, when freely suspended, pointed north-south. The magnetic compass soon spread to Europe. Columbus used it when he crossed the Atlantic ocean, noting not only that the needle deviated slightly from exact north (as indicated by the stars) but also that the deviation changed during the voyage. Around 1600 William Gilbert, physician to Queen Elizabeth I of England, proposed an explanation: the Earth itself was a giant magnet, with its magnetic poles some distance away from its geographic ones (i.e. near the points defining the axis around which the Earth turns). The Magnetosphere On Earth one needs a sensitive needle to detect magnetic forces, and out in space they are usually much, much weaker. But beyond the dense atmosphere, such forces have a much bigger role, and a region exists around the Earth where they dominate the environment, a region known as the Earth's magnetosphere . That region contains a mix of electrically charged particles, and electric and magnetic phenomena rather than gravity determine its structure. We call it the Earth's
