How does the earth's magnetic field flip
WebJan 26, 2024 · The Earth’s magnetic field protects our planet from dangerous solar and cosmic rays, like a giant shield. As the poles switch places (or try to), that shield is weakened; scientists estimate that it could waste away to as little as a tenth of its usual force. The shield could be compromised for centuries while the poles move, allowing ... WebApr 23, 2014 · A reversal of the sun's magnetic field is, literally, a big event.

WebAt a Glance. The sun’s magnetic fields flip approximately every 11 years, defining the solar cycle. The switch happens around the peak of solar activity or the time we call solar maximum. This reversal tells scientists that the second half of the solar cycle has begun. The flip will likely cause more space weather, including aurora. WebJan 27, 2024 · Scientists discovered magnetic reversals by measuring the magnetic field on either side of mid-Atlantic ridges from which molten rock is extruded like toothpaste from a tube. As it solidifies, its crystals align along the direction of the Earth’s magnetic field at the time, leaving a ‘tape recording’ of reversals.
