Our planet's magnetic field is responsible for protecting lights on the surface from the effects of solar radiation. The north and south auroras are a good example of solar particles interacting with the field. And the weakening of the field over the scuttle Atlantic exposes Earth orbiting satellites to more radiation, resulting in the likelihood of more malfunctions, damage or even blackouts. And as the field weakens, satellites will develop higher rates of charged particles. Astronauts aboard various spacecrafts will face higher risks of DNA damage and even certain cancers. And just to put things into perspective, the June magnetic field is about 147 times weaker than a typical refrigerator magnet. But even by that, it's incredible how much protection we get from it down here on Earth. And there is nothing to be concerned about with the recent weakening. This has happened many, many times in the past over Earth's history and even resulting in a complete flip of the magnetic poles. And this is all related to the patterns of circulation of the liquid metal core.
