How does Earth's magnetic field affect life on Earth? The Earth's magnetic field does not directly affect human health. Humans evolved to live on this planet. High-altitude pilots and astronauts can experience higher levels of radiation during magnetic storms, but the hazard is due to the rad...
Professor: Okay, keep in mind that solar wind is electrically charged, which means that it interacts with the magnetic field as electromagnetic theory tells us.Okay, how does it interact?Earth, magnetic field deflects most the solar wind, makes it flow around the earth without getting very clo...
3. What creates the Earth's magnetic field (and why does it move)? 3.是什么创造了地球的磁场(为什么它会移动)? 4. Will we be able to predict catastrophic weather events (tsunami, hurricanes, earthquakes) more accurately? 4.我们是否能够更准确地预测灾害性事件(海啸、飓风、地震)? 5. What hap...
Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles from the solar wind and more far-flung cosmic rays. It is continuously generated by the motion of liquidironin Earth'souter core, a phenomenon called the geodynamo. Despit...
In the study of the Earth's interior, magnetic field data is also used. How does the Earth's magnetic field help in understanding the Earth's interior? A. It has no relation to the Earth's interior structure. B. It can only tell us about the surface temperature. C. Changes in the ...

s magnetic field at the time they are formed. Analysis of the crystals showed that, at their point of formation, the Earth’s magnetic field was the weakest ever recorded — some 30 times weaker than both the current magnetic field intensity, and that measured from similar crystals formed ...
