一,电感的作用:通直流阻交流这是简单的说法，对交流信号进行隔离,滤波或与电容器,电阻器等组成谐振电路.
调谐与选频电感的作用：电感线圈与电容器并联可组成LC调谐电路。即电路的固有振荡频率f0与非交流信号的频率f相等，则回路的感抗与容抗也相等，于是电磁能量就在电感、电容之间来回振荡，这就是LC回路的谐振现象。谐振时由于电路的感抗与容抗等值又反向，因此回路总电流的感抗最小，电流量（指f=f0的交流信号），所以LC谐振电路具有选择频率的作用，能将某一频率f的交流信号选择出来。
磁环电感的作用：磁环与连接电缆构成一个电感器(电缆中的导线在磁环上绕几圈作为电感线圈)，它是电子电路中常用的抗干扰元件，对于高频噪声有很好的屏蔽作用，故被称为吸收磁环，由于通常使用铁氧体材料制成，所以又称铁氧体磁环(简称磁环)。在图中，上面为一体式磁环，下面为带安装夹的磁环。磁环在不同的频率下有不同的阻抗特牲。一般在低频时阻抗很小，当信号频率升高后磁环的阻抗急剧变大。可见电感的作用如此之大，大家都知道，信号频率越高，越容易辐射出去，而一般的信号线都是没有屏蔽层的，这些信号线就成了很好的天线，接收周围环境中各种杂乱的高频信号，而这些信号叠加在原来传输的信号上，甚至会改变原来传输的有用信号，严重干扰电子设备的正常工作，因此降低电子设备的电磁干扰(EM)已经是必须考虑的问题。在磁环作用下，即使正常有用的信号顺利地通过，又能很好地抑制高频于扰信号，而且成本低廉。
电感的作用还有筛选信号、过滤噪声、稳定电流及抑制电磁波干扰等重要的作用。
二,电感的分类:
按工作频率分类
电感按工作频率可分为高频电感,中频电感和低频电感.
空心电感,磁心电感和铜心电感一般为中频或高频电感,而铁心电感多数为低频电感.
按电感的作用分类
电感按电感的作用可分为振荡电感,校正电感,显像管偏转电感,阻流电感,滤波电感,隔离电感,被偿电感等.
振荡电感又分为电视机行振荡线圈,东西枕形校正线圈等.
显像管偏转电感分为行偏转线圈和场偏转线圈.
阻流电感(也称阻流圈)分为高频阻流圈,低频阻流圈,电子镇流器用阻流圈,电视机行频阻流圈和电视机场频阻流圈等.
滤波电感分为电源(工频)滤波电感和高频滤波电感等.
按结构分类
电感按其结构的不同可分为线绕式电感和非线绕式电感(多层片状,印刷电感等),还可分为固定式电感和可调式电感.
固定式电感又分为空心电子表感器,磁心电感,铁心电感等,根据其结构外形和引脚方式还可分为立式同向引脚电感,卧式轴向引脚电感,大中型电感,小巧玲珑型电感和片状电感等.
可调式电感又分为磁心可调电感,铜心可调电感,滑动接点可调电感,串联互感可调电感和多抽头可调电感.

信息内容：磁珠的作用在成品电路板上，我们会看到一些导线或元件的引脚上套有黑色的小磁环，这就是本文要介绍的磁珠。磁珠的全称为铁氧体磁珠滤波器(另有一种是非晶合金磁性材料制作的磁珠)，是一种抗干扰元件，滤除高频噪声效果显著。 铁氧体材料的特点是高频损耗非常大，具有很高的导磁率，使电感的线圈绕组之间在高频高阻的情况下产生的电容最校当磁珠中有电流穿过时，铁氧体对低频电流几乎没有什么阻抗，而对较高频率的电流会产生较大的衰减。对于抑制电磁干扰用的铁氧体，最重要的性能参数为磁导率μ和饱和磁通密度Bs。它的等效电路为一个电感和一个电阻串联，两个元件的值都与磁珠的长度成比例。当导线穿过这种铁氧体磁芯时，所构成的电感阻抗是随着频率的升高而增加。高频电流在其中以热量形式散发。 在低频段，阻抗由电感的感抗构成。低频时R很小，磁芯的磁导率较高，因此电感量较大，L起主要作用，电磁干扰被反射而受到抑制，并且这时磁芯的损耗较小．整个器件是一个低损耗，高Q特性的电感。这种电感容易造成谐振．因此在低频段有时可能出现使用铁氧体磁珠后，干扰增强的现象。 在高频段，阻抗由电阻成分构成，随着频率...
