也就是磁力線的方向)是環(huán)繞著電流的一些閉合曲線，磁力線和由此產(chǎn)生的磁通量(可以被看做磁力的流動(dòng))，是一些位于垂直于電流的平面上的同心圓，是圍繞產(chǎn)生它們的電流呈環(huán)形流動(dòng)的。靠近電流的地方磁場(chǎng)較強(qiáng)，離電流遠(yuǎn)的地方，磁力和磁流就越弱。磁力線方向與電流方向的關(guān)系可以用右手螺旋法則來(lái)判定。將右手握住導(dǎo)線，拇指伸直，如果拇指電流方向，彎曲的手指磁場(chǎng)環(huán)繞方向。當(dāng)線圈安裝在地板上，而助聽器佩戴者是坐著或站著時(shí)，在回路中，在頭部高度的磁力線以水平為主。這樣，在頭部高度，磁場(chǎng)的垂直部分就有一個(gè)近乎持續(xù)的量幾乎覆蓋整個(gè)房間。剛進(jìn)人回路處是個(gè)例外，那里，除了垂直部分很弱外，整個(gè)磁場(chǎng)都較強(qiáng)。以上特性很重要，因?yàn)橹犉髦械慕邮芫€圈的安裝是垂直的，它*能拾取磁場(chǎng)的垂直部分。這里已經(jīng)討論了沿著回路一個(gè)方向的電流，然而聲音是音頻信號(hào)，相對(duì)應(yīng)于原始聲波中的正壓和負(fù)壓，方向每秒會(huì)倒轉(zhuǎn)許多次。因此，循環(huán)的磁場(chǎng)每秒也會(huì)倒轉(zhuǎn)許多次。事實(shí)上，根據(jù)電磁場(chǎng)理論，正是持續(xù)改變的磁流使拾音線圈感知，產(chǎn)生一個(gè)音頻電流(地球的磁場(chǎng)不會(huì)影響線圈，正是因?yàn)榈厍虼艌?chǎng)有持續(xù)的力量和方向)。。</p><p> 所繞的線圈的圈數(shù)我們一般把它稱為線圈的“匝數(shù)“。主要性能指標(biāo)電感線圈的性能指標(biāo)主要就是電感量的大小。另外，繞制電感線圈的導(dǎo)線一般來(lái)說(shuō)總具有一定的電阻，通常這個(gè)電阻是很小的，可以忽略不記。但當(dāng)在一些電路中流過(guò)的電流很大時(shí)線圈的這個(gè)很小的電阻就不能忽略了，因?yàn)楹艽蟮碾娏鲿?huì)在這個(gè)線圈上消耗功率，引起線圈發(fā)熱甚至燒壞，所以有些時(shí)候還要考慮線圈能承受的電功率。電感量電感量L表示線圈本身固有特性，與電流大小無(wú)關(guān)。除專門的電感線圈（色碼電感）外，電感量一般不專門標(biāo)注在線圈上，而以特定的名稱標(biāo)注。電感量也稱自感系數(shù)，是表示電感器產(chǎn)生自感應(yīng)能力的一個(gè)物理量。電感器電感量的大小，主要取決于線圈的圈數(shù)（匝數(shù)）、繞制方式、有無(wú)磁心及磁心的材料等等。通常，線圈圈數(shù)越多、繞制的線圈越密集，電感量就越大。有磁心的線圈比無(wú)磁心的線圈電感量大；磁心導(dǎo)磁率越大的線圈，電感量也越大。電感量的基本單位是亨利（簡(jiǎn)稱亨），用字母"H"表示。常用的單位還有毫亨（mH）和微亨（μH），它們之間的關(guān)系是：1H=1000mH1mH=1000μH感抗電感線圈對(duì)交流電流阻礙作用的大小稱感抗XL，單位是歐姆,符號(hào)Ω。傳感器線圈分類，無(wú)錫東英電子有限公司。</p><div
