- Mere giant magnetoresistance, which debuted in commercial hard drives back in 1998, represented the first example of so-called spintronics, or electronics based not on charge but spin, the property of an electron that makes it act like a tiny bar magnet. 不过仅有在1998年的商业化硬盘上首度亮相的巨磁电阻效应才是称之为自旋电子--或非基于电荷而是旋转（电子的这个特性使它像一个小型的条形磁铁）的电子----的首个例子。
- Because the core current is somewhat symmetrical around the axis of rotation, the associated magnetic field is similar to that of a bar magnet. 因为地核流在旋转轴周围存在着一些对称，所以相关的磁场与棒磁铁的磁场相似。

- If the sun were a rigid body, its magnetic field might resemble the earth's, with symmetrical field lines like a bar magnet's. 如果太阳是一颗固体星球，其磁场或许与地球磁场相似，像条状磁铁那样具有对称的磁力线。
- If the sun were a rigid body, its magnetic field might resemble the earth's , with symmetrical field lines like a bar magnet's. 如果太阳是一颗固体星球，其磁场或许与地球磁场相似，像条状磁铁那样具有对称的磁力线。
- You can picture the innate magnetism of the electrons by imagining that each one contains a tiny bar magnet with a north and a south pole. 你可以想像，每个电子都带著一个微小而有南北极的条状磁铁，这是电子原有的磁性。
- Birds and compasses know north from south because, like a giant bar magnet, the earth's magnetic field has two poles that line up closely with the planet's axis of rotation. 候鸟与指北针都知道何为北方、何为南方，因为地球就像一条巨型磁铁棒，它的磁场有两极，且这两个地磁的磁场线和地球的自转轴非常接近。
