The single core armored cable in the list are only suitable for use for DC circuit. If used for AC circuit, non-magneticmaterial or armored by reducing magnetic loss structure must be used.
表中单芯铠装电缆仅适用于直流线路，如用于交流则必需采用非磁性材料或减少磁损耗结构的铠装。

The methods to measure the magnetic properties of weak-magneticmaterial and non-magneticmaterial, and their application, as well as the MB-2T magnetic balance developed by ourselves are presented.
To keep leakage flux to be constant, the relation is analyzed between the air gap length and the non-magneticmaterial thickness with the rare earth magnet thickness under the air gap length variety.
