Earth's Magnetic Field is Not About to Flip, Like Previously Thought

Posted by K R on

Earth's magnetic field is not about to flip. While the intensity of this field has weakened in the last couple hundred of years, researchers have found that this doesn't mean it's about to reverse. Humans have lived through dips in magnetic field intensity before. However, there are debates about whether reversals of the magnetic field in the distant past had any connection to species extinctions. Today, a magnetic field reversal would have a huge impact due to one very important thing: technology. The magnetic field deflects the solar wind and cosmic rays. This means that with a weaker field, more radiation gets through which can disrupt power grids and satellite communications. "The field may be decreasing rapidly, but we're not yet down to the long-term average," said Dennis Kent, one of the researchers, in a news release. "In 100 years, the field may even go back the other direction ." Read More: Science World Report
