"I built these spheres from this new toy I got, and after a while I managed to hang them from each other. I then spun them each in the opposite direction and watched them go. They keep going for a very long time and in the last few minutes they slow down, stop, pause for a few seconds, start going again, sometime in the oposite direction, its very cool!!!"

  • Quadratic Magnet Gate - When a small magnet is placed into the entrance of a quadratic magnet set-up, it shoots forward. No front-end loading apparent, with work applied by magnets, illustrates that magnets can be a source of free energy, like the wind.
  • The Equivalence of Magnetic and Kinetic Energy - Article by Carel van der Togt "proves that QM/QED/QCD/. ... assumes, unjustified, that the electromagnetic field is (also) conservative." Subject: Cold Fusion and Omissions in Physics. (PESWiki; Dec. 23, 2006)

Sites

  • Organic Magnets Open Vast Possibilities - Researchers at the University of Victoria have discovered new lightweight magnets that could be used in making everything from extra-thin magnetic computer memory to ultra-light spacecraft parts. "Suppose you want to make a particular shape of magnet — these magnets could be dissolved in solution and shaped into a different form." (PESN; Jan. 17, 2007)
  • Discovering Magnetism -- DVD - Howard Johnson releases a 20-minute video filmed at Virginia Tech over 20 years ago, and hosted by Dr. Gerhard Beyer, Distinguished Professor and co-researcher. In it, Johnson demonstrates a number of his unique magnetic gates, which accelerate cars on tracks using the little-known ability of magnets to fire bursts of energy like guns. (Cheniere.org; Oct 30, 2006)
  • UA physicist discovers exotic superconductivity - University of Arizona Associate Professor of Physics Andrei Lebed has discovered that strong magnetism changes the basic, intrinsic properties of electrons flowing through superconductors, establishing an "exotic" superconductivity. (PhysOrg; Aug. 16, 2006)

Magnetism

  • Magnets > Magnet Motors > Howard Johnson
    '"Discovering Magnetism'" - Video by Howard Johnson demonstrates a number of his unique magnetic gates, which accelerate cars on tracks using the little-known ability of magnets to fire bursts of energy like guns. These forces can be up to a thousand times more powerful than the base magnet strength. (Cheniere.org store)
  • Magnets > Magnet Motors > Howard Johnson
    The Secret World of Magnets - In this 1970 book, Howard Johnson claims that a magnet can fire an energy burst several hundred times stronger than its base strength, again and again…that similar magnetic poles often attract, not repel…or that the patterns of iron filings around a magnet bear little resemblance to the force fields, which are actually spinning vortices. (Cheniere.org store)
  • Two Magnet Reversal Videos - Movies Show Quick Magnetic Flips - exactly how individual magnetic bits reverse direction during writing and re-writing is still poorly understood. (Physical Review Letters; 86:728; Jan. 22, 2001)
  • Magnetic Family - The males in this Taiwanese family have something weird about their bodies that attracts metal and glass objects. Watch as the father shows a 6-pound metal iron clinging to his chest. No magnetic fields are dedected. It is not known why this occurs. (YouTube; February 15, 2007)

Magnetic Monopoles

  • Magnetism >
    'Magnetic electricity' discovered - Researchers have discovered a magnetic equivalent to electricity: single magnetic charges that can behave and interact like electrical ones. The work is the first to make use of the magnetic monopoles that exist in special crystals known as spin ice. The phenomenon, dubbed "magnetricity", could be used in magnetic storage or in computing. (BBC News; Oct. 14, 2009)

Circuitry

  • Magnets >
    Magnetic Amplifiers -- another lost technology - Reprint of a 2000 article by George Trinkaus about a technology developed by the U.S. Navy in 1951. "Mag amps not only can regulate but can magnify, oscillate, modulate, switch, pulse-generate, invert, convert, multivibrate, phase shift, and multiply.... This copyrighted work is available in a printed booklet from High Voltage Press which also sells a companion booklet called "Magnetic Amplifiers Bibliography."

Research and Development

  • Scientist Develops Programmable Magnets - Researcher and inventor Larry Fullerton of Correlated Magnetics has developed a process to "program" magnets so that they will attract or repel only another specifically programmed magnet. The process works by changing materials at the molecular level. Many potentially useful applications never before possible with conventional magnets. (Huntsville Times; Oct. 5, 2009 )
  • Sun Induces Strange 'Breathing' of Earth's Atmosphere - New satellite observations have revealed a previously unknown rhythmic expansion and contraction of Earth's atmosphere on a nine-day cycle. This "breathing" corresponds to changes in the sun's magnetic fields as it completes rotations once every 27 days, NASA and University of Colorado, Boulder, scientists said at the American Geophysical Union annual meeting. (Wired; Dec. 15, 2008)


  • Superconductivity can induce magnetism - Andrea Bianchi, a professor in the Department of Physics at the Université de Montréal, and his colleagues show that, contrary to previous belief, superconductivity can induce magnetism, which has raised a new quantum conundrum. (PhysOrg; Sept, 11, 2008)


  • Scientists find quick method to make magnets - Northeastern University researchers have broken new ground with an innovative invention of a rapid, high-volume and cost-effective one-step method for producing pure Samarium Cobalt rare earth permanent magnet materials. (PhysOrg; July 29, 2008)

Theories on Magnetism

  • Ocean Currents Proposed As Cause of Magnetic Field - "Professor Gregory Ryskin from Northwestern University in Illinois, US, has defied a long-standing convention by applying equations from magnetohydrodynamics to our oceans' salt water (which conducts electricity) and found that the long-term changes (the secular variation) in the Earth's main magnetic field are possibly induced by our oceans' circulation." (Institute of Physics; June 14, 2009) (Paper)
