如果一直挖洞，會發生什麼事？ (What If You Just Keep Digging?)
- and we should all be extremely grateful for the hot metal soup down there because its constant churning generates enormous electric currents, which in turn create the magnetic field around the Earth.
科學家們還從中學到了其他東西。
- But this gets weirder: our magnetic field sometimes actually just reverses.
這告訴我們，下面有一層液體。
電吉他的奇異物理學！ (The Bizarre Physics of Electric Guitars)
- Electric guitar pickups take advantage of the fact that when you move a magnet near a wire, the changing magnetic field causes electric currents to flow in the wire.
電吉他拾音器利用的是這樣一個事實：當您將磁鐵移至導線附近時，變化的磁場會導致電流在導線中流動。
- Electric guitar pickups take advantage of the fact that when you move a magnet near a wire, the changing magnetic field causes electric currents to flow in the wire.
就電吉他而言，拾音器中隱藏著一個線圈，琴絃本身就是移動磁鐵。
這隻鴿子為何價值百萬！？ 🕊️ (Why This Pigeon Could Be Worth Millions)
- They sense the landscape, follow the Earth's magnetic field, and somehow never need directions.
我做了三、四年，它成了世界上訪問量最大的鴿子網站。
- They sense the landscape, follow the Earth's magnetic field, and somehow never need directions.
它們能感知地形，跟蹤地球磁場，而且從不需要方向指引。
未來 100 兆年後，將會發生什麼事？！ (This Is What Will Happen in the Next 100 Trillion Years)
- In 2.3 billion years from now, the outer liquid core of Earth will freeze, which means that Earth will lose its magnetic field forever.
23 億年後，地球外層的液態內核將凍結，這意味著地球將永遠失去磁場。
- In 2.3 billion years from now, the outer liquid core of Earth will freeze, which means that Earth will lose its magnetic field forever.
到 28 億年後，地球表面的平均溫度將急劇上升到 149 攝氏度。
NASA拍攝的太陽閃焰引發極光奇景！BBC Global (Watch the spectacular solar flares causing the aurora | BBC Global)
- but the rest are caught in our magnetic field and drawn to both poles, leading to geomagnetic storms that penetrate our atmosphere.
有些會被偏轉開，但
- the rest are caught in our magnetic field and drawn to both poles, leading to geomagnetic storms that penetrate our atmosphere.
剩下的則被我們的磁場捕獲並帶往兩極，進而引發地磁風暴，滲透我們的磁層。
西班牙體驗Lexus懸浮滑板！超酷炫！ (Riding the Lexus hoverboard in Spain)
- A special property of these type 2 superconductors is that when they're cooled down to a critical temperature, they exhibit properties that alter and manipulate any magnetic field around them.
這些 2 型超導體的一個特殊性質是，當它們冷卻到臨界溫度時，它們會表現出改變和操縱周圍任何磁場的特性。

2089天內可能發現外星生命！🚀 (We Might Find Alien Life In 2089 Days)
- And this metallic liquid hydrogen generates an incredibly powerful magnetic field, almost 20,000 times stronger than Earth, if you measure at the same distance away.
而這種金屬液態氫會產生無比強大的磁場，如果在同樣的距離測量，其磁場強度幾乎是地球的 2 萬倍。
