I will post on auction the field coil and iron coremagnet on auction later. However, to replace the magnet require technical skill and tool.
我随后会拍卖励磁和导磁柱，但是，改变磁路需要点技术和工具。

The value of this flux can easily be deduced from the difference between flux densities at magnet poles and core poles shown in Fig. 5, and the gap area.
这个磁通值可以容易地从图5中永磁极的磁密和铁极磁密之间的差值和气隙面积求出。

Especially in high-performance oxygen to soft magnet materials and magnetic core has a strong technical force.
