永磁体被认为只适用于制造小而弱的磁体。然而，通过引入饱和铁极，可以制造出比过去更高强度的磁体。冷却磁体进一步在很大程度上增强了磁场强度。我们已经证明了一个永久偶极磁体可能超过一个典型的永磁体的3倍以上。一个新的挑战是为加速器应用构思这样的磁体，其中经常需要依赖时间的交变磁场。
Permanent magnets are believed to be applicable only to make small and weak magnets. It is possible, however, to make a magnet with much higher strength than those in the past by introducing a saturated iron pole. Cooling down the magnet further enhances the field strength to a great extent. We have demonstrated that a permanent dipole magnet exceeding a typical permanent magnet more than by factor 3 is possible. A new challenge is to conceive such magnet for an accelerator application where time dependent alternating field is often requested.
