Magnetic Hysteresis

Edward Della Torre is professor of engineering and applied science at The George Washington University, Washington, D.C. Dr. Della Torre’s principal research is in the analysis of magnetic materials by numerical micromagnetic modeling and Preisach modeling. His studies of accommodation and aftereffect led to the accommodation model in 1994 and the Preisach-Arrhenius model in 1998. The simplified vector model, also presented in 1998, has made vector calculations possible in real time. These extensions of the Preisach formalism developed by Dr. Della Torre have been used in the field to understand and quantitatively predict the behavior of magnetic materials. A Fellow of the Institute of Electrical and Electronics Engineers and the American Physical Society, Dr. Della Torre is currently president of the IEEE Magnetics Society. He has published extensively in the field and is the coauthor of two books, The Electromagnetic Field (Allyn and Bacon, 1969) and Magnetic Bubbles (North Holland, 1975).
