book has long been considered a reference publication within the magnetics industry. Soft magnetic composite (SMC) materials and their uses in electrical machines have undergone significant development in the past decade.

The major advantages of the materials include isotropic magnetic and thermal properties, very low eddy current loss and relatively low total core loss at medium and higher frequencies, and low cost fabrication with good tolerance and surface finish using the. Publisher Summary. Nanoparticles are defined as materials whose particle sizes are in the range of 1– nm.

One of the major changes in the properties of nanoparticles is the significant increase in the number of atoms/molecules on the surface of particles, and hence availability of effectively high surface area compared with bulk material. In the field of electrical machines, the actual research activities mainly focus on improving the energetic aspects; for this reason, new magnetic materials are currently investigated and proposed.

The book offers superior coverage of electrical, optical, and magnetic materials than competing text. The author has taught introductory courses in material science and engineering both in academia and industry (AT&T Bell Laboratories) and has also written the well-received book, The Material Science of Thin Films (Academic Press).

Semiconductor materials are nominally small band gap defining property of a semiconductor material is that it can be doped with impurities that alter its electronic properties in a controllable way.

Materials for electrical engineering Introduction Most types of electrical equipment rely, for their safe and efficient performance, on an electrical circuit and the means to keep this circuit isolated from the surrounding materials and environment.

Many types of equipment also have a magnetic circuit, which is linked to the electrical circuit by the laws outlined. Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments.
