| 摘 要： | 定量讨论了导磁园柱筒对外界磁场的屏蔽作用,指出被屏蔽空间的磁场强度反比于园柱筒的磁导率,并随筒壁厚度的增大而减小。若把载流导线置于园柱筒内,由于被屏蔽载流导线将不受磁力作用,但作用在园柱筒上的磁化力是存在的。

| Abstract: | The effect of a permeable cylinder to screen an exterior magnetic field are studied mathematically, we can see that the strength of the field inside the cylinder varies inversely with the permeability and the thick of the cylinder.
If a current-carrying wire is placed inside the cylinder, due to the wire is screened, there is no magnetic force acting on the wire, but a magnetizing force is acting on the cylinder. |
