在混合永磁体中添加软铁提高磁场强度
Enhance the Field Strength by Adding Soft Iron in the Hybrid Permanent magnet
摘要：
永磁体具有体积小、结构紧凑的特点，特别适合于狭小的空间。采用软铁的辅助作用，可以大大提高磁场，并能很好地控制磁场的均匀性。大多数永磁体具有对称结构，可选用软铁作为浮动磁极，使其标量势保持恒定，并作为介质收集永磁块的直接磁通，然后将磁孔中的间接磁通释放到附近的返回轭。提出了一种利用轴向磁化和径向磁化永磁体设计和制作混合型永磁振子的磁通量法。作为扩展设计实例，设计了变梯度永磁四极子和变梯度六极子。它们都由两个嵌套的混合永磁环组成，其中的磁极用于控制磁场质量，收集来自外环的磁通量，阻挡斜四极和高次谐波。
英文摘要：
Permanent magnet has a small and compact structure, is especially suitable for a narrow space. With the aid of soft iron, the magnetic field can be increased much more and the field uniformity can be well controlled. Most Permanent magnets have a symmetry structure; the soft iron can be selected as the float magnet pole to keep its constant scalar potential, and take roles as media to collect the direct flux from the permanent blocks, then release indirect flux in magnet aperture and to the nearby return yoke. This paper presents the magnetic flux method to design and fabricate a hybrid permanent dipole by using axially and radially magnetized permanent blocks. A variable gradient permanent quadrupole and a variable gradient sextupole are designed as the extend design examples . They all consist of two nested hybrid permanent rings, where the iron poles are used to control the field quality, collect the magnetic flux from the outer ring, block the skew quadrupole and high order harmonics.
