Stories about: magnetic poles

Solar Magnetic Field Reversals Occur Asymmetrically In two papers to appear in print soon, astronomers and solar physicists provide more details about how the Sun reverses its magnetic fields, swapping its north and south magnetic fields between them. The studies also provide detailed maps of solar magnetic field asymmetries that accompany the process. Our parent st... 21 April 2012 03:16 GMT Magnetic Monopole 'Cousins' Obtained at NIST Everyone knows that one of the basic traits magnets have is sporting two poles. If you break a larger magnet into two smaller ones, then each of the them will have a “north” and a “south pole.” For some time, experts have theorized that it could be possible to create magnetic monopoles, as in ... 7 October 2009 06:01 GMT Oceans May Be Moving the Poles Around Gregory Ryskin, a physicist and researcher at the Northwestern University, is part of a growing group of researchers who are currently advocating the hypothesis that the magnetic poles of the planet are actually being pushed around by oceanic currents. When this idea first appeared, a large controversy ensued, and it... 22 June 2009 04:42 GMT
