Why is the north magnetic pole moving? (No more than 8 words) 相关知识点: 试题来源: 解析 地核液态流动变化 地球的磁场主要由外地核液态铁镍合金的对流运动产生。这些液态金属的流动形态受地核内部热量交换、地球自转科里奥利力等复杂因素影响,会随时间发生不规则变化。这种流体运动的动态调整直接导致地球磁场的...
The non-ideal effects required to break magnetic field line connections scale as e σ , so the breaking of connections is inevitable for σ sufficiently large—even though the current...doi:10.1080/10420150.2017.1398242Allen H. BoozerDepartment of Applied Physics, Columbia University, New York, NY...
The Earth’s core is magnetic because it has a molten outer core that is in constant motion. The motion of the molten outer core produces an electric current which then produces a magnetic field. Iron loses its magnetism when it’s heated to a few hundred degrees, yet Earth’s core – ...
Explain why the temperature at the equator is always hot and the temperature at the poles is always cold, despite the passage of seasons. Why magnetic induction is more at its ends? What is the most important element for creating a magnetic field, and why? Which end of the magnet is...
In science, navigation is defined as the process of attaining accurate planning and positioning to follow a route. Navigation is used to getting the ships and aircraft from place to place. Answer and Explanation:1 Magnetic declination is also known as magnetic variation. It is defined as t...
My friend today showed me the magnetic attachment which I was not aware of. I researched this and I am aware this magnet does not support charging. However, compared to her pro and pencil 2, the magnet strength seems to be weaker than hers (on my iPad) when snapping on the 1st gen ...
Why is this voice so magnetic [羞嗒嗒][羞嗒嗒]还唱过玫瑰花的葬礼和素颜,我关注的唱歌博主里好多都喜欢许嵩的歌哈哈哈哈太爱了 http://t.cn/A6qBmUDk
Samsung has been using MST technology to offer a mobile payment solution for a long time. MST or the Magnetic Secure Transmission is a technology, that is also found on credit and debit cards, which securely stores the data on a magnetic strip. ...
the birds engage in a process that produces something called heteroaglandular poison — i.e. poison produced as a result of consuming a certain toxin which is then re-used by the bird for its own defenses. This happens when the birds eat poisonous plants or animals, and since the birds ...
C. they could have something to refer to in the following task D. they might compare the difficulty level of the two tasks 2. How did the participants who had received magnetic pulses do in the syllable task, compared with those who hadn’t? A. They relied more upon conscious analysis....
