A geomagnetic storm occurs when a violent solar wind hits the earth and severely distorts the earth s magnetic field 地磁暴起因是由于猛烈太阳风冲击地球，使地球磁场急速变形而造成的。
Abstract ； on the " earth ' s magnetic field reversal " one said , we have not experienced a human nor historical records 摘要；关于“地球磁场逆转”一说，我们人类并没有经历过，也没有历史记载。
We also know that the magnetic field of the sun reverses as well every 11 years , whereas the earth ' s reverses irregularly 我们还知道太阳的磁场也发生倒转? ?每们年一次，而地球磁场的倒转并无规律。
Nasa fired three microsatellites into space wednesday to study the earth ' s magnetic fields , a week after an earlier launch was scrubbed 的方式将3颗微型卫星送上了太空，开始了对地球磁场的研究工作。
The earth is shielded by its magnetic field , which forms a kind of bubble within the stream of charged particles emanating from the sun 不过太阳风不会直接撞上地球和大气层，因为有地球磁场屏蔽著地球。
Informative as it was , the ldef study was conducted in low earth orbit , well within our planet ' s protective magnetic field Ldef的研究固然提供了有用的信息，却是在低轨道实施，位于地球磁场绝佳的保护伞之下。
In other words , how can the wind overcome the barrier of the geomagnetic field and drive the motions of the plasma inside the magnetosphere 换言之，即太阳风是如何克服地球磁场的阻碍，进而驱动磁层里的电浆运动？
Angelopoulos says a finding will help scientists know more about the threatening solar storms and how our planet ' s magnetic field works 称，发现结果将帮助科学家了解更多有关太阳风暴的危险性和地球磁场的运作原理。
Olson is particularly interested in how the earth ' s core and mantle interact to produce geomagnetic fields , plate tectonics and deep mantle plumes 欧尔森对于地核与地函如何交互作用而产生地球磁场、板块运动和地函深部的烟流特别感兴趣。
Occurrence of geomagnetic storms i . e . severe distortion of geomagnetic field of the earth can induce electric current in oil pipelines and electric cables 对输电系统及输油管的影响地磁暴即地球磁场急速变形会使输油管及电缆产生电流。
