mumetal

基本解释

Shielding attenuation of Mumetal and other materials at several frequencies.
高导磁合金等几种材料在不同频率下的磁场衰减特性。
Figure 16 compares a 30-mil thickness of Mumetal with various materials at several frequencies.
从图中可以看出：与其它材料相比，频率低于1kHz时，高导磁合金的性能最优；
For improved low-frequency magnetic shielding, a shield consisting of a high-permeability magnetic material (e.g., Mumetal) should be considered.
要改善低频磁屏蔽的效果，就要考虑用高导磁率的磁性材料（即高导磁合金）来制作屏蔽体。
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.
虽然高导磁合金有诸多优点，但是这种材料用起来并不是很方便，如果受到强磁场作用而达到磁饱和的话，这种材料就不再具备任何优势了。
It shows that, below 1 kHz, Mumetal is more effective than any of the other materials, while at 100kHz it is the least effective.
而当频率为100kHz时，高导磁合金的性能最差。
