Page 22 Above (2.30) last sentence should be: Thus (2.29) becomes:
Page 36 Fig. 3.2 Second column should have E=V/l
Page 38 should have RFe= 1.5/[(2000)(12.57E-7)(.01)] = 59666 (E3.1.1)
Page 52 should have W=(0.125)2/[2(12.57E-7)(0.1)(0.1)(1)] = 62.2 J (E4.2.2)
This energy of the reluctance method is about 56% lower than the 141.65 J

A tutorial paper will be presented the morning of May 15th 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 2nd 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 email@example.com.
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.

“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 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.
