但是，这是由于使用了场的语言，所以才形成了提出这个问题的观念。

If the bar magnet is simply held stationary near the coil, no current is indicated.

如果磁棒单纯静止在线圈附近，就检测不到电流。

Both the sun's magnetic field and the Earth's magnetic field can be oriented northward or southward (Earth's magnetic field is often described as a giant bar magnet in space).

太阳和地球的磁场都可以定向为南极和北极（地球的磁场通常被描述为一个在空间中的巨大条形磁铁）。

In a single bar magnet as shown to the right, they attempt to form closed loops from pole to pole.They never cross one another.They all have the same strength.

磁场线总是寻求阻力最小的路径从一极到另外一极，但是不能相交。，所以在空间的分布是一个逐渐扩大的圈子。

RGM resistance is to use metallic glass enamel coating on the top bar magnet, has excellent impact resistance characteristics and high temperature stability, heat dissipation is good, wide range of resistance at low prices, is widely used in high-power devices, is a new generation of surface mount circuit design the best choice.

RGM 电阻是用金属玻璃釉镀于磁棒上面，有着极佳的耐冲击特性及高温稳定性，散热性好，阻值范围广，价格便宜，广泛应用于高功率设备，是新一代表面贴装线路设计的最佳选择。

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。

Each atom behaves like a tiny bar magnet, and when the crystal is cooled to near absolute zero, the atom-magnets align.

有时候，四面体四个角中的三个排列在一起，使得四面体的中心产生磁单极子。
