根据交变磁场测量法(ACFM)的基本原理,设计了一种由激励线圈和感应线圈组成的交变磁场传感器,可对空间“点”磁场进行测量。
According to the basic principle of alternative current field measurement (ACFM), the alternative current field sensor was designed, which was made up of drive coil and induction coil.
所述磁场发生器可以优选地通过激励线圈(11,13)实现,所述传感器元件(12)通过磁阻元件,例如gmr元件实现。
The magnetic field generators may preferably be realized by excitation wires (11, 13) and the sensor element (12) by a magneto-resistive element, for example a GMR element.
