Why Earth is a Magnet: Understanding Our Planet’s Magnetic Field and Its Life-Sustaining Role Discover the fascinating science behind Earth's magnetism in this instructional video. Learn how the molten metal core generates the magnetic field, the formation of magnetic poles, and how this invisible force protects life by deflecting harmful solar radiation. Perfect for science enthusiasts and students eager to explore Earth's interior dynamics and its vital role in sustaining life. This clear and

Earth's magnetic field isn't constant. It flips. North becomes South and vice versa. These geomagnetic reversals happen every 200,000 to 300,000 years and were actually overdue. During the flip, the field weakens, exposing us to solar radiation and possibly disrupting satellites, power grids, and animals' migratory instincts. The last full flip happened 780,000 years ago. We don't know when the next will come, but the signs are already being studied. | Auto Viral
