What Makes Earth’s Magnetic Field Change Direction?

The video explores Earth's magnetic field reversals, explaining the Dynamo theory and the role of Earth's core. It discusses how scientists study these changes using volcanic rocks and the potential link between plate tectonics and field reversals. Recent research suggests a pattern between subduction and reversals, with randomness in the process. The video concludes that Earth's magnetic field can reverse without external triggers like asteroids.
