mumetal

基本解釋

Shielding attenuation of Mumetal and other materials at several frequencies.
高導(dǎo)磁合金等幾種材料在不同頻率下的磁場衰減特性。
Figure 16 compares a 30-mil thickness of Mumetal with various materials at several frequencies.
從圖中可以看出：與其它材料相比，頻率低于1kHz時(shí)，高導(dǎo)磁合金的性能最優(yōu)；
For improved low-frequency magnetic shielding, a shield consisting of a high-permeability magnetic material (e.g., Mumetal) should be considered.
要改善低頻磁屏蔽的效果，就要考慮用高導(dǎo)磁率的磁性材料（即高導(dǎo)磁合金）來制作屏蔽體。
However, Mumetal is not especially easy to apply, and if it is saturated by an excessively strong field, it will no longer provide an advantage.
雖然高導(dǎo)磁合金有諸多優(yōu)點(diǎn)，但是這種材料用起來并不是很方便，如果受到強(qiáng)磁場作用而達(dá)到磁飽和的話，這種材料就不再具備任何優(yōu)勢了。
It shows that, below 1 kHz, Mumetal is more effective than any of the other materials, while at 100kHz it is the least effective.
而當(dāng)頻率為100kHz時(shí)，高導(dǎo)磁合金的性能最差。
