style="text-indent:25px">釹鐵硼主要優(yōu)點(diǎn)：性價比高，并且在機(jī)械方向上擁有不錯的特性缺點(diǎn)在于：居里溫度點(diǎn)偏低，同時溫度特性較差，并容易發(fā)生粉化腐蝕，必須通過調(diào)整其化學(xué)成分和采取表面處理方法（如鍍鋅等）使化學(xué)性能上得到改進(jìn)，才能達(dá)到我們需要的實(shí)際應(yīng)用要求。而鐵氧體永久磁鐵是一類擁有鐵磁性的金屬氧化物。就電特性來說，鐵氧體永久磁鐵的電阻率相比于比金屬與合金磁性材料來要大得多，并有稍偏高的介電性能。釹鐵硼永久磁鐵和鐵氧體永久磁鐵磁鐵的區(qū)別主要有以下幾點(diǎn)：1.鐵氧體永久磁鐵性能不如釹鐵硼永久磁鐵。2.價格上.鐵氧體永久磁鐵的要比釹鐵硼永久磁鐵磁鐵便宜很多。3.釹鐵硼永久磁鐵耐溫很好，而普通的釹鐵硼永久磁鐵通常只能80度，超過了這個工作溫度就會出現(xiàn)退磁情況。4.鐵氧體永久磁鐵穩(wěn)定性非常好，它本身是氧化物，很穩(wěn)定，上海辦公自動化磁鐵直銷廠家，釹鐵硼永久磁鐵是合金，上海辦公自動化磁鐵直銷廠家，上海辦公自動化磁鐵直銷廠家，及其容易氧化、必須做涂層保護(hù)。多角度多方位滿足您對異形磁鐵各種尺寸的測量要求。上海辦公自動化磁鐵直銷廠家</p><div

style="text-indent:25px">所有的磁鐵都是有正負(fù)極之分的，磁鐵的周圍是存在磁場的，當(dāng)磁鐵相互靠近的時候，由于磁場的互斥作用，兩塊相同極的磁鐵要想吸在一起好像有股力量一定要讓它們分開的，當(dāng)兩個不同極的面靠近一起時就會吸引。簡單來說，磁鐵的排斥是由于磁鐵中的磁場作用產(chǎn)生的。這就是我們平常所學(xué)的物理學(xué)中的異性相吸，同性相斥。能吸引鐵、鈷、鎳等物質(zhì)的性質(zhì)稱為磁性。磁鐵兩端磁性強(qiáng)的區(qū)域稱為磁極，一端稱為北極（N極），一端稱為南極（S極）。實(shí)驗(yàn)證明，同性磁極相互排斥，異性磁極相互吸引。物質(zhì)大都是由分子組成的，分子是由原子組成的，原子又是由原子核和電子組成的。在原子內(nèi)部，電子不停地自轉(zhuǎn)，并繞原子核旋轉(zhuǎn)。電子的這兩種運(yùn)動都會產(chǎn)生磁性。但是在大多數(shù)物質(zhì)中，電子運(yùn)動的方向各不相同、雜亂無章，磁效應(yīng)相互抵消。因此，大多數(shù)物質(zhì)在正常情況下，并不呈現(xiàn)磁性。無錫電鍍磁鐵哪家好磁鐵生產(chǎn)廠家稱物理上，磁鐵能吸收鐵、鎳和鈷的物體。</p><div
