About admin

John Brauer received three degrees in electrical engineering: a Bachelor’s from Marquette University, and Masters and Ph.D. degrees from the University of Wisconsin, Madison. He is a registered Professional Engineer. His engineering employment began at A. O. Smith Corporation, where in 1972 he began developing electromagnetic finite element software to analyze electric motors. The software was the first of its type to be commercially available, and led to his subsequent employment by the MacNeal-Schwendler Corporation and later by Ansoft Corporation. In 1998 he became employed by Milwaukee School of Engineering (MSOE) as Adjunct Associate Professor in the Department of Electrical Engineering and Computer Science. At MSOE he teaches an annual short course on magnetic actuators and sensors. He also consulted extensively for Ansoft Corporation, Rockwell Automation, and other companies. He has served on the boards of the Applied Computational Electromagnetics Society and the International Compumag Society. He has published 160 technical papers and has contributed to several books. In 1995 he was elected a Fellow of the IEEE “for contributions to finite element analysis of electromagnetic devices.” In 2000 he received the Third Millennium Medal for his service to the IEEE. In 2006 he authored the Wiley IEEE Press book Magnetic Actuators and Sensors.

“Magnetic diffusion delays in steel and permanent magnets when coil currents are turned on and off,” has been accepted for the Magnetics 2014 Conference, Orlando, FL, January 29-30, 2014. This new paper is partly based on the 2nd edition of Magnetic Actuators and Sensors by John R. Brauer, to be published by Wiley IEEE Press in late 2013.

I am available to teach you about magnetic actuators and sensors

I teach an interactive seminar “Magnetic Actuators and Sensors” over the telephone and internet for your company or institution.  The seminar can be tailored to your needs but usually consists of four sessions of three hours each.  Only a college freshman’s understanding of basic math and physics is needed as a prerequisite.  Watch introductory video at:
