查询词典 bar magnet

We only observe the small portion of the magnetic field that extends to the surface and beyond, where its basic structure is a dipole that is, a simple north south field like that of a simple bar magnet.

我们仅仅观察到扩展到地表和地表以外的磁场的一小部分，在这里它的基本结构是一个偶极子，就像一个简单的棒磁铁一样是一个简单的南北极磁场。

Fluid iron in the planet's core acts like a huge bar magnet, creating a relatively weak magnetic field.

地心处的液态铁就像一个巨大的条形磁铁，会形成相对较弱的磁场。

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。

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。

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）。

Around a bar magnet , for example, the l s of force point from the north pole to the south.

例如，在磁铁棒周围的磁力线从北极指向南极。

Like a simple bar magnet, this field's primary magnetic flux is directed out from the core in the Southern Hemisphere and down toward the core in the Northern Hemisphere.

地磁就如同一根普通的磁铁棒，而这个磁场的主要磁通量是在南半球由地核向上穿出，并在北半球向内进入地核。

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。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
