Practical Magnetic and Electromechanical Design by Mark A. Juds is now available at www.bookbaby.com.  The book focuses on calculations of magnetic fields by the reluctance method, which can be implemented on computer spreadsheets.  In several places it references my book Magnetic Actuators and Sensors, 2nd ed., Wiley IEEE Press, 2014.

Mark A. Juds, reviewer and contributor to the 2^nd edition of Magnetic Actuators and Sensors, retires this month after 37 years with the Eaton Corporation.  Mark holds 70 U.S. patents and 46 European patents in the areas of sensors, power switching, magnetic actuators, mechanisms, and capacitors.  He has 45 publications, has given 62 invited presentations outside of Eaton, and has taught courses at the Milwaukee School of Engineering and at the University of Wisconsin-Milwaukee.  He also volunteered for many years as Chair of the Milwaukee Chapter of the IEEE Magnetics Society and as a mentor encouraging students in STEM.  I wish Mark a happy retirement, which he so richly deserves.

I have been invited to give a presentation titled “My Great Uncle Carl Quickert, Washington County Historian” by the Washington County Historical Society, West Bend, WI on April 5, 2017.  You are welcome to attend the talk beginning at 11:30 AM at the Society’s Old Courthouse Museum, 320 South 5^th Avenue, West Bend, WI.  Carl Quickert was my mother’s uncle, and as I state in the Preface of my book Magnetic Actuators and Sensors, 2^nd ed., her love of books, inspired by her Uncle Carl, was passed on to me.

I plan to be in San Diego, California during the IEEE MMM/Intermag Conference from January 11 thru January 15, 2016.  See www.magnetism.org  . I would be happy to meet you then to answer any questions about Magnetic Actuators and Sensors, 2^nd Edition.  To arrange a meeting time and place, please email me at  jbrauer@ieee.org .

In March 2015 the ANSYS Advantage magazine (volume IX, issue 1) will contain an article on magnetic nanoparticle force computations written by John R. Brauer. The article contains material excerpted from Chapter 7 of Magnetic Actuators and Sensors, 2nd edition, as well as new enhanced color displays of magnetic fields and forces. The article will appear at www.ansys.com/magazine .

A talk will be given at 5:30 PM on September 17, 2014 by John Brauer.  Its title is

MAGNETIC PARTICLE FORCES FOR ACTUATORS, RECYCLING SEPARATORS, AND BIOMEDICAL APPLICATIONS.

Magnetic volume force densities are computed using finite element analysis.  Computations on small permeable particles are shown to agree with a classical formula for magnetic separators.  Such forces are important for magnetic particle brakes and clutch actuators, and for recycling separators of steel waste.  Computations are also made for biomolecular screening using magnetic beads such as those made by GE Healthcare.

This talk is based largely on parts of Chapters 5 and 7 of Dr. Brauer’s book Magnetic Actuators and Sensors, 2^nd edition, Wiley IEEE Press, 2014.

The talk is sponsored by the IEEE Magnetics Society Milwaukee Chapter and the IEEE Engineering in Medicine and Biology Society Milwaukee Chapter.   It will take place at the Milwaukee School of Engineering, Todd Wehr Auditorium, 1025 N. Broadway, Milwaukee, WI 53202.  Admission is free to all, and snacks will be provided.

A tutorial paper will be presented the morning of May 15^th at the Electrical Manufacturing and Coil Winding Expo in Milwaukee, WI.  Titled “Variations of Coils and Steel for Optimum Design of Magnetic Actuators,” the paper is authored by Mark Solveson and John Brauer.  Based on the 2^nd edition of Magnetic Actuators and Sensors published in early 2014, the tutorial will last almost an hour.  For complete seminars for your staff, contact the author at jbrauer@ieee.org.

Wiley IEEE Press has now published the Second Edition of Magnetic Actuators and Sensors by John R. Brauer, copyright 2014. It is about 25 percent larger than the first edition (2006). Besides many updates and clarifications, it has new sections on topics including:
Mechatronics, analogous circuits, Halbach magnets, magnetic volume forces, magnetic bearings, magnetic separators, saturable magnetic infusion and effusion, encoders, current sensors, GMR spin valve sensors, Chattock coils, SQUID magnetometers, actuator systems for 2D planar motion, actuator design optimization, and digital hydraulic valves.
