Materials for Permanent Magnet Applications

  • Alex Goldman
Part of the The Springer International Series in Engineering and Computer Science book series (SECS, volume 505)


The permanent magnet materials of this chapter are among the few magnetic materials that do not operate in an electromagnetic manner. Thus, no windings are used to create the magnetic field in the material. Most of the rest of the magnetic materials in this book do operate electromagnetically. Sometimes, the current used is DC, but mainly it is ac of various frequencies. As a result, the next chapter will deal with the electromagnetic usage of magnetic materials at DC and low frequencies for power applications.
