"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!!!"

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)
Types of Magnets - There are three main types of magnets: Permanent, Temporary and Electromagnets. Each has its own application. Permanent retain their magnetism when not in a magnetic field while temporary magnets lose it when removed from a magnetic field.
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 )
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)
Directory:Magnets > Directory:Magnets > China Lowers the Boom on Rare Earths - Monday, China embargoed exports of rare earth elements to the United States. Rare earths are integral to most all cutting edge technologies including renewable energy systems (e.g. Directory:Magnet Motors), and China controls 93-97% of the world supply. "Whenever you have a shortage of raw materials in the world, it historically has led to war." (5 Min. Forecast Oct. 20, 2010)Directory:Batteries / Directory:Magnets > Directory:Magnets > $1 Trillion Afghan Mineral Deposits Will Affect Green Technologies - It turns out that there's more than the opium trade and Caspian oil line to protect in Afghanistan. The New York Times reported that the country has $1 trillion in untouched mineral deposits, including an abundance of rare earth elements utilized in many green technologies and lithium, which is the key ingredient in batteries for computers and electric vehicles.

Directory:Magnets > Directory:Magnets > Rare Earth Mining Firm Molycorp to Provide U.S.-Based Product - Molycorp, which wants to mine for rare earth elements in California, filed for an IPO today to raise up to $350 million. The company has developed a plan to mine rare earth elements in Mountain Pass, California and then turn rare earth oxides into things like magnets for wind turbines. (GreenTechMedia April 16, 2010)Directory:Magnets > Directory:Magnets > U.S. Sitting on Mother Lode of Rare Tech-Crucial Minerals - An Idaho company called U.S. Rare Earths holds the only known U.S. deposit of heavy rare earths with a concentration worth mining, according to a recent report by the U.S. Geological Survey (USGS). If developed, such deposits could help the U.S. avoid a possibly crippling rare earth shortage in the next decade. (LiveScience March 8, 2010) Directory:Environment / Directory:Magnets > Directory:Magnets > Inside China's secret toxic unobtainium mine - Raising questions about the world's source of Neodymium ... "I was the first Western journalist to set foot inside the mine. What I saw at Baiyun Obo and the poisoned refineries it feeds raises disturbing questions about the future we are buying into - and who will control it." (Daily Mail UK Jan. 10, 2010)
Concern as China clamps down on rare earth exports - Neodymium, used in permanent magnets, is one of 17 metals crucial to green technology. There’s only one snag – China produces 97% of the world’s supply. And they’re not selling. During the past seven years it has reduced by 40 per cent the amount of rare earths available for export. (Independent, UK Jan. 2, 2009)
Directory:Environment > Earth-Friendly Elements, Mined Destructively - Some of the greenest technologies of the age, including e-cars and wind turbines, are made possible by rare earth minerals. Just one problem: These elements come almost entirely from China, from some of the most environmentally damaging mines in the country, in an industry dominated by criminal gangs. (NY Times Dec. 26, 2009)
