顺磁性的,指物质在外部磁场中能被微弱吸引的性质,通常用于物理学和化学领域。

用法要点

句型搭配

常用于描述物质的性质,如“be paramagnetic”或“exhibit paramagnetic behavior”,在科学语境中强调其与磁场的相互作用。

• The material is paramagnetic.
• It exhibits paramagnetic properties.

介词用法

常与介词“in”连用,表示在某种条件下或环境中,例如“in a magnetic field”,用于说明顺磁性发生的场景。

• paramagnetic in nature
• paramagnetic in a weak field

语域说明

主要用于学术和技术领域,如物理学、化学和材料科学,在日常对话中较少使用,属于专业术语。

• paramagnetic resonance
• paramagnetic materials

基础例句

This metal is paramagnetic, so it's slightly attracted to magnets.

这种金属是顺磁性的,所以能被磁铁轻微吸引。

In science class, we learned that oxygen is a paramagnetic gas.

在科学课上,我们了解到氧气是一种顺磁性气体。

The paramagnetic material doesn't retain magnetism after the field is removed.

顺磁物质在磁场移除后不会保留磁性。

You can test if something is paramagnetic by using a simple magnet.

你可以用一块简单的磁铁来测试某物是否具有顺磁性。

高级例句

The paramagnetic properties of the compound were analyzed using electron spin resonance spectroscopy.

该化合物的顺磁性质通过电子自旋共振光谱进行了分析。

In materials engineering, paramagnetic alloys are often used in sensors due to their sensitivity to magnetic fields.

在材料工程中,顺磁合金因其对磁场的敏感性常被用于传感器。

常见错误

❌ 错误:This material is paramagnetic, so it repels magnets.
✓ 正确:This material is paramagnetic, so it is weakly attracted to magnets.

错误在于混淆了顺磁性和抗磁性;顺磁性物质被微弱吸引,而非排斥,应正确描述其与磁场的相互作用。

❌ 错误:Paramagnetic means it has strong magnetism like iron.
✓ 正确:Paramagnetic means it has weak magnetism and is only attracted in an external field.

错误在于高估了顺磁性的强度;顺磁性是弱磁性,不同于铁磁性的强磁性,应强调其依赖外部磁场且吸引力微弱。

近义词辨析

ferromagnetic

铁磁性物质能被强烈磁化并保留磁性,而顺磁性物质仅在外磁场中被微弱吸引且不保留磁性。

Iron is ferromagnetic and can become a permanent magnet, whereas oxygen is paramagnetic and only shows weak attraction.

diamagnetic

抗磁性物质在所有磁场中都被微弱排斥,而顺磁性物质在磁场中被微弱吸引,两者都涉及弱磁性但方向相反。

Water is diamagnetic and repels magnets slightly, while aluminum is paramagnetic and attracts them weakly.
