Magnetic Field


News
  1. Earth's Weakening Magnetic Field (Scientific American)
      "Earth's magnetic field, which protects the planet from huge blasts of deadly solar radiation, has been weakening over the past six months, according to data collected by a European Space Agency (ESA) satellite array called Swarm."

      "Floberghagen hopes that more data from Swarm will shed light on why the field is weakening faster now."

      "Still, there is no evidence that a weakened magnetic field would result in a doomsday for Earth. During past polarity flips there were no mass extinctions or evidence of radiation damage. Researchers think power grids and communication systems would be most at risk." 07-14
