PSMA Reprints Classic Magnetics Text

The Power Sources Manufacturers Association (PSMA ) has announced the availability of a reprint of the classic book "Applications Of Magnetism" authored by the late J. K. Watson and originally published by John Wiley and Sons in 1980.

According to Ed Bloom "This classic book, written by one of the most respected teachers in the field of magnetics, makes the principles of applied magnetics accessible to the practicing electronics engineer. With emphasis on practical design, the text presents the relevant principles of physics, circuit analysis, simple models and the calculations involved in designing a circuit or a magnetic device. No prior knowledge of the physics of magnetism is assumed ─ material properties are explained in a step-by-step manner, with special attention to their effects on the volt-ampere characteristics of a magnetic device, and to the physics of magnetic domain processes. Applications of magnetics, including those associated with power electronics circuits, are covered as well as reluctance modeling methods for transformers and inductors."

Copies of this practical design treatment of magnetics will be available for sale at this year’s Applied Power Electronics Conference (APEC 2008) in Austin, Texas, February 24-28, 2008 and through the PSMA website. Copies will sell for $100, but members of PSMA companies can obtain a copy for $50.

In the past three years, PSMA has reprinted three other classic books on magnetics including "Transformers for Electronic Circuits" by the late Nathan R. Grossman, "Soft Ferrites – Properties and Applications" by E.C. Snelling and "Electronic Transformers and Circuits" by the late Reuben Lee and Associates. A limited number of the Snelling and Lee books are still available through www.psma.com.
