It can not only measure DC current magnetic field but also alternative current magnetic field. This system has small volume, high capability, and wide frequency range.
本智能磁场测量系统既适合测量直流磁场，又可测量交变磁场，且体积小，性能高，适用频率范围宽。
The results show that permeability decreases and cut-off frequency increases with the increase of DC bias. Permeability varies linearly in the certain range.
研究表明：偏置直流的增加，降低了材料的磁导率，提高了截止频率，并且在一定偏置直流范围内，磁导率呈线性变化。
