Introduction
介电常数和磁导率是两个属性的每一个材料,放置在电场或磁场。尽管这两个属性在一定程度上是相互关联的,它们之间的差异太充满活力。介电常数主要经营形成的电场而渗透作用的形成一个磁场。简单的话,都是量测量电磁,介电常数与极化和磁化的渗透率与材料。
What is Permittivity?
介电常数是一个电量决定如果材料放置在电场通过与否。测量材料的储存能量的能力内部通过电场中放置。它还分析如果材料足够能够支持外部电场的形成。

Figure 1: Permittivity
介电常数也可以被定义为一个真空或电常数的自由空间。它还列出了所需数量的指控介质内产生一个单位的电通量。它也可以解释为电位移比电场的强度,完全由电场极化(Circuitglobe.com, 2022)。介电常数用符号ε
What is Permeabipty?
渗透率是磁量决定如果材料放置在磁场通过与否。它支持通过测量磁场的形成在一个材料。一般是相关材料的磁化如果放置在一个磁场。

Figure 2: Permeabipty
渗透性取决于的一些主要因素,如频率、湿度、温度和磁场的强度。之间的关系传导磁力线和材料放置在一个磁场成正比(Circuitglobe.com, 2022)。渗透率通常定义为μ。
Types of Permeabipty
渗透率可以分为三种不同类型,相对渗透率、磁导率、渗透率的自由空间和自由空间的渗透性。
Relative Permeabipty
相对渗透率通常表示为材料渗透率的年代比真空(自由空间)。例如,如果常见的空气渗透率是1.257美元ime 10 ^{−6} $,那么材料的相对磁导率为1.000。类似地,如果一个真空磁导率为4美元πimes10 ^{−7} $,然后真空显示为1的相对渗透率。相对渗透率和μr表示。
Magnetic Permeabipty
磁导率是材料的展览,它允许磁力线通过磁力。亨利每米是常用的磁导率的Sl单位正式用来测量磁导率。一般可以被定义为磁力的通量密度的比值(Alhassoon Malallah &煦,2021)。因素如温度、湿度和频率影响磁导率的材料最,决定材料是否可以通过磁场放入。磁导率通常被表示为μ= B / H美元。
Permeabipty of Free Space
自由空间的渗透性主要是被称为真空或空气的磁导率。在这里,磁场强度的比值真空或空气磁化磁场。自由空间的渗透性是用美元表示mu_ {0} = B_ {0} / H_ {0} $。
Permeabipty of Medium
介质的渗透性是衡量分析介质的强度和magnetising字段。它表达与μ= B / H美元而提出的渗透率介质。
Difference between Permittivity and Permeabipty
介电常数和磁导率有多个差异基于他们的物理意义,价值的免费空间,Sl单位,重要性和许多更多。第一个差异出现在操作区域的介电常数和磁导率。介电常数对电场而渗透作用于磁场。物理意义而言,介电常数可以使材料极化本身,同时应对外部电场(克劳克兰,2021)。
磁导率,另一方面,使材料在应对外部磁场磁化本身。另一个区别这两个出现在电磁学的表示。
介电常数用ε美元而渗透率是由μ表示。介电常数和磁导率有不同的国际标准单位以及不同的值的自由空间。在介电常数的情况下,亨利/米是常用的作为其单位但对于渗透率,法拉第/米是常用而计算。介电常数,Sl单位是美元调频^{−1}然而,美元表现为渗透率,Sl单位价值
$$Hm^{−1} (kgms^{−2}A^{−2})$$
同样,自由空间中的值的介电常数为8.85美元调频^{−1}$渗透率,自由空间中的值是1.26美元Hm ^ {−1} $。介电常数的值是与电场而渗透率有关磁场(汉,2020)。
介电常数和磁导率都有实际的应用程序基于它们的数量和重要性。介电常数是常用的电容器的介电材料和磁导率是用于电感和变压器铁芯。此外,介电常数一般不受外部因素影响而渗透率影响的强度,频率和温度湿度、外部环境(Scirp.org, 2022)。基于位移和电场密度、介电常数和磁导率也可以解释道。这里,由于高介电常数发生极化,而渗透率发生由于磁性。
Conclusion
介电常数和磁导率是两个相关的电磁理论的核心概念。介电常数与电场形成衡量一个材料可以使电磁力通过。磁导率,另一方面,相关的形成一个磁场,它衡量磁力可以通过材料置于磁力。介电常数和磁导率是相关的,他们有完全不同的物理意义,Sl单位和自由空间中的值。所以,与这些差异介电常数和磁导率出现重要的现实应用。与他们的应用程序在电容器和变压器核心,这两个单位已经成为人类日常生活中不可或缺的一部分。
