Is Earth’s Magnetic Field Flipping Soon?


While any magnetic-field flip would still be thousands of years away, the effects could be profound on technology, if similar to today’s technology. This is because the weaker magnetic field would be somewhat poorer at shielding Earth against the solar wind (the constant stream of charged particles emanating from the sun) and cosmic rays (blasts of radiation from deep space). Magnetic compasses would not be as accurate, and satellites that monitor the weather or carry telecommunications signals could be disrupted.
